Sombra's hack should just be instant with a CD, I'm not really seeing the need for it to have the wonky charge up it has currently. Would make it way more useful in fights
It's pretty fast as it is (like 1.2s?), especially since you can prefire it, and people do need some sort of counterplay.
I'd like them to up the duration on it a tiny bit. And I also thought yesterday it might be cool if it actually disoriented the target more. Like glitched out their vision in addition to removing directional audio. That might be too annoying or inconsistent for people to stomach, though.
The problem isn't with getting hacks off, honestly. Sombra would be fantastic if the game were 7v7. But in a 6v6 context, and especially with the meta the way it is now, and healing being so readily available and so powerful ... she just doesn't do enough burst damage to be worth picking ahead of more conventional DPS. Also, her kit is way too situational and encourages gimmicky strategies. The health pack stuff is a little silly as it stands.
