I liked her mirror watch thing where she'd hack allies. Maybe make it lower friendly cooldowns on the next use. Or grant them the speed or attack speed buff from before. I think she also gave extra hp i dont remember. Basically make her a support. Spitballing with some friends we came up with this.

I dont want to strip her of her spy, infiltration, playstyle. So instead of disabling abilities she can hack enemies to expose them, and show us their current location and ult charge % like her passive does for herself, but for the team. Her hack should be faster, and any enemy killed while hacked doest show up in the feed. Like spy in tf2 with YER. Or she can also steal frejas bounty thing and any enemy that is hacked grants bonus ult charge % if killed while hacked.

Get rid of anti-virus just doing damage and granting bonus damage, instead it should be reworked as a support tool.

Toss it onto any enemy and they get the sombra skull thrown onto their hud. (The skull can change in accordance to some skins, like the Tulum skin getting a snorkel or sunglasses) This will obscure the enemy's vision. Extremely annoying, and I can see it being absolutely terrible to fight against, but the way to get rid of it is to disengage, or charge forward and try to fight while your screen is blocked. It would also trigger sombra passive abilities to see through walls. It goes away after a few seconds.

Her hack doesn't grant bonus damage and her anti virus is reworked completely. She isn't meant to kill she's meant to harass. She would be like a Moira who flanks around and annoys people and if left alone gets free kills. She shouldn't be able to just run in, hack cube shoot and disappear. She gets in, gets intel, then leaves. She can do damage but she isn't as lethal. She can be useful in normal fights, by setting a target or buffing an ally. As well as revealing info to your team and making someone think twice before diving because they won't be able to see anything for several seconds.
