If they reverted the speed change for

Lucio’s speed momentum for his wallride when they changed it and then say “we’ll see how this goes” why cant they do that with Sombra’s speed, and say “we’ll see how it goes”

With the other buffs she was given, Geoff believes she would be too strong if she retained her speed, or could contest the objective (the latter making 100% sense with a character that can stay indefinitely invisible).

they have also made wallride easier and more accessible for everyone…just like in the same sense of making infinite stealth by making it easier and accessible for everyone

Making a character more accessible isn’t a negative thing, even if it means slightly lowering their top potential. It closes some doors, sure, but opens others. Seems like most don’t care about the new possibilities ( for example: Lucio wall riding 90 degree turns effortlessly now).

but if they decided to revert it for lucio, what is stopping them from reverting it for sombra, its still in PTR let them test it and see how it goes instead of automatically jumping the gun and getting rid of it
