I can only agree here!
As a Sombra main it really feels terrible to play in the current meta. I just learned a bit of Mccree and its worlds of diffrences of how much more useful I am as a Mccree even tho I just stareded playing him and play Sombra for 300h since she came out.
Could you ask your friends: What they think of this: 👾 Sombra Buff/Rework [Workshop Included!] ?
I know its nothing thats gonna make her really viable but I think it would be a great start to boost her power, fix alot of the issues she has while making her more fun, even a bit more skillful (tho she already meeds lot of learning) and way less clunky. All traded for something noone liked from the beginning anyway.
