The problem with heroes like Sombra, and even heroes like Ana, is that if you tweak them too much they can end up being OP due to the nature of their kit. So like you said, there’s that sweet spot, which clearly the devs are trying to find by testing things out in PTR.
I am trying to figure out how any of that sounds like a bad thing. She still has the same core kit but now they’re playing around with the kit to see what can be buffed without making her OP. A hack preventing a reload is absolutely huge. That would make a target absolutely useless.
And infinitely stealthed Sombra that can contest a point? That’s insane.
