That’s totally wrong,
If this would’ve been the case then they shouldn’t have nerfed Doomfist and Mei. Reaper and Hanzo also recieved nerfs, Symm got nerfed.
Doomfist was nerfed because he was the only dps hero good against GOATS as well as double shields. He got nerfed due to complains from tank and support mains, and not willing to switching to his counters.
Now they nerfed Mei just because of the same reason, she was good against Rein zarya comp.
They just want Rein, Zarya, Ana in every single game (Their pickrates and winrates even prove this)
So its tanks and supports, that game designers are listening to.
