Overwatch：最強ヒーローティアリスト

The current Overwatch 2 meta favors high-mobility, high-utility heroes capable of generating decisive advantages through transformative ultimates and consistent fight presence. Recent balance changes have clarified the gap between dominant and situational picks, with S-tier heroes pulling clearly ahead across all three roles.

Kiriko remains the premier support pick, combining teleport mobility with the game-saving Protection Suzu and lethal Kunai headshot potential that forces opponents into constant caution. Her ability to cleanse key debuffs and reposition instantly makes her invaluable in virtually every team composition at every level of play.

Mauga dominates the tank role through relentless dual-minigun pressure and powerful self-sustain, making him an ever-present threat in prolonged team fights that opponents cannot afford to ignore. Reinhardt complements that aggression with reliable barrier protection and the fight-ending Earthshatter ultimate, providing the structured frontline presence many compositions depend on to function. Zarya rounds out the tank tier with exceptional bubble management and a Graviton Surge ultimate that enables some of the most punishing team wipes in the game when paired with the right damage dealers.

In the damage category, Sojourn excels through her Railgun charge mechanic and Disruptor Shot, consistently producing high-value eliminations that punish grouped opponents and rapidly shift momentum. Tracer applies relentless flanking pressure, using Blink and Recall to harass backlines and secure picks that force opponents to rotate and break formation. Together, these six heroes demonstrate the highest ceiling across diverse maps and compositions, with their mobility tools, sustain, and utility generating opportunities that heroes in lower tiers simply cannot replicate.

A tier is densely populated with strong, reliable picks across all three roles. Lucio and Baptiste provide exceptional support value through speed boost utility and high-throughput healing respectively, while Moira and Lifeweaver offer meaningful sustain in the right compositions. On tank, D.Va, Sigma, Ramattra, Junker Queen, and Winston each bring distinct tools that reward skilled play and map awareness. In the damage role, Genji, Ashe, Soldier: 76, and Sombra all deliver consistent output and team utility, making them dependable choices that fall just short of S-tier dominance.

B-tier heroes remain viable but require more favorable conditions or specific team compositions to reach their ceiling. Pharah, Echo, Hanzo, Widowmaker, Junkrat, Mei, Hazard, Bastion, and Doomfist all offer situational value in the damage role, while Orisa and Wrecking Ball can be effective tanks on maps that suit their playstyles. None are unplayable, but each carries notable limitations in the current meta.

C-tier heroes struggle to keep pace with the demands of the current meta and are generally outclassed by alternatives in their respective roles. Mercy lacks the proactive impact of other supports, relying heavily on teammates to generate value rather than creating advantages independently. Roadhog's self-sustain has been diminished by repeated adjustments, leaving him vulnerable in a meta that punishes slow, predictable tanks. Reaper faces persistent mobility and range issues that make it difficult to reach priority targets against well-coordinated teams. Symmetra's utility is highly situational, limiting her viability to a narrow set of maps and scenarios where her teleporter and turrets can be effectively deployed.
