Look I've said this before, healers need a nerf. This role is plagued by so many bad players that its become very apparent that they're trying to dictate the game's balance.
Dive was not too bad, you just had to ping and coordinate heals but support players cant do that so instead of learning the game they spam Q as much as they can. And its really fucked up the game because those chink devs are dying on the OP support ult hill which is the worst way to balance this game
