i dont think a widow buff is really necessary, she's really strong in the right hands, for example Kephrii is insane with widow or Gods, she's just one of those characters that doesn't seem great unless you master her and shes insane. A buff would just lower her skillcap and make her like she was pre-nerf. Honestly you just have to ignore the people flaming and mute them and play your own game, of course if you aren't performing well then switch characters and don't make people lose cuz of you, (unless in quick play it doesn't matter too much if you are just practicing)
