I’ve seen this being suggested and although it could work in some games, OverWatch isn’t one of them.
The Devs really focus on that fast paced aspect of the game itself; it’s why they nixed Symm’s healing turrets since they were clunky and awkward to use and a game like this. Something like a ghillie suit doesn’t seem to fit the flow of this game.
Sure Junkrat did need something, I played him when he was a troll pick. And Hanzo did too he was just an easy Dive target that lacked any real damage outside Scatter.
Junkrat and Hanzo did need something to increase their viability…but what was given just made their viability in damage too great.
(Oh hey look viability is unbalanced again!)
