Didn’t play Overwatch for a while, and don’t see any changes for the better. Just going further in same direction.
You don’t mix casual and competitive sides in your game. TF2 was balanced, as far as it was possible, for casual audience, with competitive players having tools to black list certain classes/weapons and customize their experience.
You can optimize fun out of game and make it competitive, but it doesn’t work in other direction. Blizzard tried to do that, but it was unachievable goal.
