It’s interesting you say this, because the tank main in me should agree with you, but actually hates it, while the support main in me also hates it.
Hypothetically, heroes like Pharah, JR, Hanzo and Mei should be bigger issues for tanks than heroes like Ashe, Soldier, Cree and Bap, yet their ability to consistently put damage on enemies makes them far more a nuisance. In addition to this issue, by their very nature, hitscan play deeper, more static playstyles as tanks really struggle to engage these heroes due to the positions they choose to play from.
At days end, we have seen hitscan dominate the game, and the tank player’s response has been Double Shield, Ball and Hog, all of which are miserable to play against.
The most reasonable solution to preventing any one meta from dominating the game is hero bans.
