I think Ana has been a problem for a while (years). I used to argue her being the most picked hero in the game for years was problematic. I slowly excepted that the devs don’t care about that, which they confirmed recently.
OW2 though brings in a new perspective. It is one thing having pick-rate being irrelevant to your balancing philisophy but another to treat a hero with favoritism and allow her to be an exception to your own rules in OW2. Ana shouldn’t be treated special.
AUG 2019: Ana needs a nerf!
JUN 2019: Why is Ana allowed to be OP?
SEPT 2020: Mercy is going to receive nerfs soon
In all these years. Nothing. Honestly I just think the balance devs are incompetent. How can this be healthy for the game? Ana could very well be perfectly balanced on paper but it doesn’t mean that it should be acceptable for her to be the most picked hero in the game for the rest of time. If it continues in OW2, the game will die incredibly quickly.
