The thing with heroes is that for one you need to feel like you are the hero, that you do insane amounts of damage but at the same time they really need to balance them so they aren't completely invincible, timers is a terrible idea because it forces you to go out in the middle of an army and die before the timer runs out, I saw that happen a lot in beta and it didn't bode well nor was it fun. The one thing that runs through my mind though when facing a hero is that I know I cannot win unless they are at 15% health or lower, rather than letting them kill me I impact grenade myself since dying to them would still count as a death on my part but if I kill myself then they are denied the kill, sure it sounds bad but I'd rather be able to kill the hero somehow or not let him kill me, to stand there and take the death isn't fun nor is it worth dying for since no one wants to die in a competitive game anyway.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
