My problem with Doomfist is his right click. It's literally a redefined version of the hook combo with Roadhog, except with a much shorter cool down, and therefore makes the Roadhog nerfs even more baffling than before.
Agreed, a pet peeve of mine with him is that Hog Hook and Rein charge give you a chance to react. The Rocket Punch is so fast that all he has to do is aim at doors and wait until someone goes through for an easy hit. Nothing can block it other that Orisa and even then she's have to be hella fast in seeing him.
As for his size I think he is huge, but it's required otherwise with his insane mobility he'd be very difficult to take down on top of having insane burst potential.
