Overwatch Season 4 Tier List: Best Heroes After the D.Mon Hotfix

Season 4: Heroes of Busan turned Overwatch's tank role upside down, and the hero balance team hasn't stopped tuning it since. D.Mon, the newest MEKA Squad pilot, launched on August 11 and immediately became the hero everyone had to answer. Two follow-up rounds of changes — a full balance patch on September 8 and a hotfix on September 17 — have since pulled her back toward earth while shaking up damage and support at the same time.

This tier list ranks every hero touched by those two patches, reasoned from Blizzard's own official patch notes. It's our opinion, built from what actually shipped rather than raw pick rates, so treat the placements as a starting point for your own testing rather than gospel.

01What Changed Since D.Mon Arrived

D.Mon debuted as part of the Reign of Talon: Season 4 story arc, giving the MEKA Squad's Yuna Lee a Plasma Saber for close-range duels and a Power Barrier to protect her team. She was strong enough out of the gate that Blizzard trimmed her twice in five weeks. The September 8 patch cut her 6v6 armor from 325 to 300 and her Plasma Saber damage from 65 to 60, while quietly speeding up her Call Mech transformation from 1.95 to 0.95 seconds and tightening her Portable Fusion Repeater's spread from 2 to 1.75 degrees. The September 17 hotfix went further, cutting her armor again — 325 to 275 in 5v5, 300 to 250 in 6v6 — along with her Focused Fusion damage (45 to 36) and Fusion Repeater damage (16 to 15, with a longer cooldown).

Elsewhere, the same September 8 patch reshaped the damage and support rosters. Freja lost a chunk of her burst after her weapons proved too strong, Kiriko had her healing and Protection Suzu trimmed for the same reason, and Baptiste got a straight-up buff to Immortality Field that makes it far harder to punch through. None of that happened in a vacuum — it's worth keeping this running changelog open if you're grinding ranked this week.

02Tank Tier List: D.Mon Comes Back Down to Earth

• S-Tier — D.Va: The only tank in either patch to get a pure buff. Her mech's base health rose from 175 to 200 in 5v5, with no offsetting nerf anywhere in her kit. She's the safest tank pick on the roster right now.
• A-Tier — D.Mon: Two rounds of nerfs have taken real bite out of her, but the mobility buffs from the September 8 patch — a faster Call Mech transform and a tighter Fusion Repeater spread — are still in place. She's no longer the automatic must-pick she was in August, but a well-piloted D.Mon still punishes bad positioning.
• A-Tier — Mauga: His base armor dropped from 150 to 125, but Blizzard reverted an earlier spread nerf on his single-fire Chainguns, restoring some of his close-range accuracy. The developers' own read is that he "continues to have high durability and damage output," and the September 8 notes back that up.
• A-Tier — Winston: A Barrier Projector cooldown cut from 12 to 10 seconds outweighs the one-second duration trim. More frequent barriers means more engagement windows, which matters more than the barrier lasting a beat longer.
• B-Tier — Wrecking Ball: Adaptive Barrier's duration fell from 1.5 to 1 second, shrinking his engage window. Still a strong dive pick, just less forgiving on the initiation.
• B-Tier — Zarya: Particle Barrier's cooldown grew from 11 to 12 seconds, meaning less personal shielding uptime across a fight. A minor nerf, but it adds up over a full match.
• B-Tier — Domina: A 6% ultimate cost reduction is a real but modest buff. Worth a second look if you'd written her off, but not a tier-defining change.

03Damage Tier List: Sierra and Freja Trade Places

• S-Tier — Sierra: Her Helix Rifle projectile speed jumped from 90 to 120, a huge reliability gain that more than makes up for the small damage trim (9 to 8.5 on both Helix Rifle and Tracking Shot). Blizzard said her "damage output has remained high" while her "weapon reliability has been limited" — this patch fixed the second half of that sentence.
• A-Tier — Widowmaker: Untouched by either patch beyond a sound-effect update. No nerf is itself a signal that she's sitting in a healthy spot.
• B-Tier — Freja: Her Relentless Barrage now refunds 5 bolts instead of 8, and both her Revdraw Crossbow and Take Aim explosion lost damage. Blizzard was explicit that "recent changes have significantly increased Freja's damage output," so this is a correction, not a gutting — she's still a strong pick, just no longer a top-tier outlier.
• B-Tier — Vendetta: Faster Palatine Fang swings (both the initial delay and the horizontal arc) are offset by slower recovery on Whirlwind Dash and Sundering Blade. The net effect favors clean hit confirms over aggressive dashing.
• B-Tier — Anran: A shorter Vermillion Revival cast time is a real quality-of-life buff, but the reduced Dancing Blaze visual clutter makes her easier for enemies to read and react to.
• C-Tier — Torbjörn: The throw-range buff to Anchor Bolts was scaled back from 50% to 25%, and the Rivet Gun's secondary-fire spread only tightened slightly. Incremental, not transformative.
• C-Tier — Junkrat: Concussion Mine's cooldown dropped from 8 to 7 seconds, which helps his signature mine-jump combo cycle faster, but Nitro Boost's bonus speed was cut from 125% to 100%. Blizzard's own framing — that he's "struggled to remain effective" since an earlier nerf — suggests this patch is a partial fix rather than a full recovery.
• C-Tier — Symmetra: Teleporter placement range fell from 30 to 25 meters and its reuse cooldown grew, both aimed at her long-distance repositioning power. A clear step down for coordinated dive comps built around her.

04Support Tier List: Baptiste Rises as Kiriko Gets Reined In

• S-Tier — Baptiste: Every Immortality Field number moved in his favor: unkillable health up from 20% to 25%, its own health pool up from 125 to 150, and its cooldown cut from 22 to 20 seconds. That's a straightforward, uncomplicated buff to one of the strongest defensive cooldowns in the game.
• A-Tier — Wuyang: Restorative Stream's regeneration rate climbed from 12.5% to 15% per second, though it now drains faster once you lose line of sight (5 seconds down to 3). Net positive for sustained healing in extended fights.
• A-Tier — Jetpack Cat: A small trim to Biotic Pawjectiles' damage and healing (4.5 to 4) is the price for how strong recent mobility changes made this hero. Even after the correction, Jetpack Cat's movement kit keeps it near the top of the support pool.
• B-Tier — Kiriko: The most heavily nerfed support this cycle. Healing Ofuda's projectile speed dropped from 24 to 18 meters per second and its seeking range shrank from 35 to 30 meters, while Protection Suzu's invulnerability window and explosion radius both shrank. Blizzard called her "highly effective" pre-patch, and these changes target exactly the utility that made her a default pick.
• B-Tier — Brigitte: A straight swap of 25 health for 25 armor changes how she takes damage rather than how much she can take overall. Better against sustained chip damage, slightly worse against burst — largely a wash unless you're tracking specific matchups.
• B-Tier — Zenyatta: Harmony Orb now falls off a target 2 seconds sooner after you lose line of sight. A minor tax on his healing uptime against mobile targets.

05Best Heroes to Learn Right Now

If you're picking a hero to main heading into the next few weeks, lean toward the ones that came out of this balance cycle with buffs rather than nerfs — they're less likely to see another correction before Season 5.

Quick-Pick Heroes by Tier

1. 1Pure buff this cycle: mech health up from 175 to 200. The default safe pick.S-Tier
2. 2Faster Barrier Projector cooldown means more frequent engagement windows.A-Tier
3. 3Helix Rifle projectile speed jumped from 90 to 120, fixing her main weakness.S-Tier
4. 4Untouched by either patch — a sign she's already balanced well.A-Tier
5. 5Immortality Field got buffed on every axis: health, uptime and cooldown.S-Tier
6. 6Higher sustained healing rate makes them a strong pick for extended fights.A-Tier

06How the Meta Might Shift Before Season 5

D.Mon's two-patch nerf arc is a familiar pattern for a new hero launch — Blizzard tends to overshoot on power for the marquee release, then walk it back over the following month once enough high-level data comes in. Her mobility kit is still intact, so don't be surprised if a third adjustment targets her Power Barrier or Plasma Saber range rather than more flat number cuts. On the support side, Kiriko's utility nerfs read as the bigger long-term story: she's been a default pick since launch, and taking Protection Suzu and Healing Ofuda down a notch at the same time is the kind of double nerf that usually sticks for a while.

Whichever heroes you settle on, re-check this list after any hotfix — Blizzard has shipped balance changes roughly every one to two weeks since Season 4 launched, and a single number tweak to a cooldown or a projectile speed can be enough to move a hero a full tier in either direction.
