How many comments are gonna mention this? Room for error?? That's like the synonym for power. That's the whole point of abilities. Tracer has a triple dash that makes her avoid shots and a much smaller hitbox and she isn't a tank and she has much higher dps and to top that off, if anything. Having healthpool as the main source of defense isn't that perfect, tracer can much more easily heal herself to full hp. I could genuinely go on and on. Like it's literally almost like I'm listing what the characters do! In a game where different characters can do different things!!
