Blizzard was pretty good at making Diablo 3 very comfortable on consoles. There are actually a lot of things on the console version of Diablo 3 vs PC that I liked. Although the PC version was better, it definitely wasn't required. I imagine this is the same for Overwatch. They are treating it separate with specific character buffs/debuffs so it's not going to be a flop like console TF2.
