Well if you would go so far every hero has a 10-second stun they can do its called killing And every hero is better at it then Sombra
Her power was always known no the pros didn’t just realize her power it was just way more effective to play someone that can kill This clip is from danteh he is a Pro player and plays Sombra / Tracer:

She was used as a Surprise pick they just didn’t had any strat to counter her that’s why we always saw it mirrors and we saw her being forced out multiple times in the last games as they slowly found some strats that worked and it wasn’t because she was good it was because they didn’t had time to think of one.
I didn’t suggest any Dmg or direct buffs to hack yes a threshold for hack seems like a buff for it but with as less as 10 - 15 dmg (which was the number I named) it just keeps hack from bracking from small splash dmg and far away (close range weapon) shots.
More speed makes her more useful in team fights without hack or EMP and Visuals make teamwork easier with her she is just way to hard to play with as a Team that’s why she is hated.
Nerfing EMP charge rate how I said to allow these buffs would make her CC even rarer
I agree on you that buffing any CC would be bad for the game but I don’t agree on buffing Sombra would be bad for the game her CC will stay the same while the rest of her kit will get better.
I hope that you understand that as a Sombra main in Plat getting someone the Team to throw just because you pick Sombra is not something that should happen. The buffs I told you above would be more powerful at lower ranks and it would probably more nerf her then buff her in pro play and in that playstyle (which I really hate EMP bot is no fun to watch or to play).
And a lot of bugs is underestamating things: Even more Sombra Bugs in 1.26/1.27/1.28 [With Video's] - #2 by Inky-11160
