He's right though. Just dps didn't know how to actually kill a moth, and people didn't play wonston much back then. Now that she's nerfed to shit. People still don't know how to kill her and people still don't play wonston much now.
Rez in general in a fps competitive game is a bad idea. Watching OW league and hearing the commentators be all hype when someone got kills only the then call "but mercy picks them back up" in a flat tone says it all. Not exciting to watch and BS to play against.
She had a working kit, the problem was you had mercy one tricks who liked to play hide and seek and get the big rezzes without checking for ults. That just wasn't fun to play with
I completely agree, I MUCH preferred Mercy 1.0, and I still maintain that Mercy 1.0 required more skill to perform well with. I wouldn't even have minded a nerf to the res area, or reverting back to when she could get killed while resurrecting.
