It seems like Blizzard is being very slow and careful with the way they issue nerfs.
If they nerf her/McCree into high heaven and completely dumpster them, the balance of the entire game might go out of whack. There are 20 characters - it's a complex ecosystem.
I think Blizzard is going to watch closely how this patch effects the game, and then if it's not enough they'll make more patches. This is the best route if we want Overwatch to be balanced.
i agree, itd be very easy to make those two completely useless, so its nice that theyre doing it bit by bit
unrelated note, i think lucio needs some changes. his shockwave should have a lower cooldown, less of a blowback, and should be able to deflect projectiles like rockets and junkrats grenades. then they should take away the completely pointless wall running. i think this makes him a more effective support character.
