Constant counterpicking. You don’t see this in other roles, but for tanks it’s like the second the game starts getting challenging tank players just insta swap to Orisa/Zarya and the game is no longer fun. And the second I start doing a little TOO well as tank the enemy team is gonna go Ana or Bastion or the billion other tank counters and force me to play Orisa, Zarya or Sigma or just lose and get hit with the ‘tank diff’.
