Ana has been a hot topic recently, with this being only amplified by Mauga. Ana is currently needed to keep some of the current tanks in check. How are you planning to curb Ana's complaints and incredibky high pick rate while making sure some of the tanks currently being held back by anti dont profit too much from ana nerfs?
Or are currently no Ana changes on the horizon? Or are you planning to nerf some tanks in the same patch as the patch with the Ana changes?
Anti-Heal is a useful mechanic for the overall health of the game as it helps to ensure that healing never gets too far out of control. The complaints around it feeling oppressive are understandable (as debuffs are never something players enjoy being affected by) and we'll be looking for ways to soften its impact while keeping Ana a viable hero.
The simplest solution here is just decreasing the duration of the effect though there is certainly a point where it swings from feeling OP to not useful enough if the time is too low to really capitalize on.
The reaction around it does also suggest that healing is probably too impactful overall so we'll be looking to address that in the near future as well, whether that is handled in the case of individual heroes like Roadhog Take a Breather or more systemically.
