characters that can go invisible are automatically my bane
I like sombra's character but I hate her abilities
it's like they're trying to compensate for the disaster that was the ARG by making her overpowered
She doesn't seem that overpowered on paper to be honest. At optimal range, she has less damage than Tracer and seemingly worse accuracy. She can teleport, but not instantly. I mean, she /could/ teleport instantly but she's not going to go very far. Yes, she can go invisible but there's like infinity plus 1 counters to this. Especially when you consider that she doesn't immediately go invisible. The first being that if she takes any damage she breaks stealth. Junkrat, Mei, Bastion, Winston, Zarya, D.Va, another Sombra and Reinhardt could probably easily accomplish that. Maybe even Roadhog by complete accident from some crazy stray projectile. She's also detected by Hanzo, Widowmaker, and another Sombra. Her hacking isn't instant and like her stealth, is also interrupted by damage. It seemingly has short range, maybe like, half hook range. This really only makes it useful against tanks, and still opens her up to abuse. Assuming it's a visible effect while she's attempting to do it, any of the tanks could just "Boop" her. Otherwise, it might actually have use.
And if you have complaints about her ult, you might as well not play Overwatch. Because other than Tracer, every hero's ult is bullstuff.
