Personally I think that the mild knocks that you take from the explosive weapons (that aren’t “tactical” like the mine or concussive) actually add to the games immersion beyond just helping them against hitscan type opponents. Adds some extra… feedback…(?) other than just your health dropping down from getting hit by a bomb.
To each their own though I guess. While this sorta thing would directly benefit me (favourite Damage is McCree) I don’t think its a good idea to remove things when you’re trying to improve a hero. Their already getting rid of Zarya’s beam going from little to big mega noisy beam at high energy (play a lot of zarya so I’m more biased on this one).
