The cooldown timer on reincarnation makes me laugh. Yeah, Sam, you aren"t going to surprise anyone with that. If anything, they are going to be laughing when you use it, and will mow you down again (given that since you are using it, you died, so they are probably capable of repeating that which killed you in the first place). This was never a big "OMG broken" thing, in part because of the cooldown, and in part because you don"t get anywhere near 100% hp/mana back, and in a large PvP setting you"ll likely be easily killed again. And don"t tell me you are actually considering spending two talent points on Imp reincarnation, either...
I mean, if a single char suicides into you, and you kill them off, then maybe I could see the use. If one (or even a few) true PvP players gets into your little picnic party, reincarnation will just make them LOL, (or possibly annoy them all to hell).
