Rolling discussion

Hey guys I would like to have a little chat with those who are actually interested in about rolling a wotlk character
I usually prefer PvP, but PvE is WoW factor that is definetly not going to be ignored in my (lordareon:p) experience... Ive been thinking about rolling warlock or hunter these are some pros and cons from my perspective and iam quite curious about your point of view...

Hunter pros
Can rely on himself / can fight pretty much anyone

cons
ammo (dont know how huge this problem actually is big/small)
mana? (still dont have own resource)
PvE?

Warlock pros
Great PvE
fear/mana drain:D
switching affliction/destro in pvp is not very punishing

cons
hard to master/ can be literally destroyed with few classes if not played properly or even if did so

so thats about it sorry for my ******ed english and thanks for helping with my dilema
