Hmmm, I guess it all depends on the day I've been having.
I dont mind dying to backpedaling(everyone does it at some point), or ever retreating ranged cowardice, even a buncha cav pine cones dont hurt my feelings too bad most days.
What makes me really rage inside is watching people run headlong into groups of enemies and then bitch about ganking, and then bitch some more about how their team is a bunch of useless pussies. Freakin Lemmings... tolerable on most days, enervating as hell during Strat battles.
I think the worst ragers are evident, they just report everything no matter what, im down for sum tom-foolery most maps :p
