The only characters I fear on console are Reaper and Genji. Everyone else can be contained fairly easy. Reaper's shotgun range is fucking absurd, he's tanky, he drops any character in the game in just a few shots and it doesn't require extreme accuracy. He gets a free heal for killing people, 8(!!) shots with a quick reload, easiest team wipe ult in the game...I could go on all day about this fuck. I die inside every time I hook him and a shot+melee doesn't kill him.
The McCree FTH nerf set Reaper free on console, there is no true hard counter to him on console, IMO. A great Reaper in a good team is extremely hard to overcome.
Genji is impossible to hit, and even though Winston counters him, there's so many characters that destroy Winston, you don't hardly ever see anyone try and counter pick him to Genji.
I mainly play tanks in competitive, and I know Reaper is a tank killer, but I simply think he's too good at it. I'd just like to see a more severe damage drop off, it's way too long at the moment, you can do actual impactful damage to Pharah at times when she's in the air, so silly to me.
