Besides, very rarely do you have a perfect game, your death gets to mean something far more than the majority of DPS heroes. Focus down kog? I think people will learn to think twice about doing that, and if he hits as hard as he looks like he's going to it's going to be a rock and a hardplace.
Also....read the freaking thread, kog GETS TO MOVE during those four seconds before he explodes, you can ram your face down their throats and go in a blaze of glory. They do NOT have to sit around near his corpse.
