The Overwatch 2 team is tweaking "roughly half" of the playable heroes in the upcoming midseason patch.
Blizzard recently gave every Damage hero a new passive that allows them to reduce foes' healing by 20% for two seconds—when you consider that they also got a self-healing passive lately alongside tanks, they aren't doing bad. For a competitive shooter all about team synergy and party composition, that's a pretty seismic shift, so the team is now making roster adjustments in an attempt to reach that unattainable 'balance.'
