Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, I've been thinking about playing on the PvP server and I just had a question about class choice. I've been a long time retail player who quit during Cata. My only question is this: if I role a resto shaman will I have trouble getting into raids endgame or are they in demand?

Resto Shaman is the only type of shaman you will not have an issue with getting a raid spot.

Chain heal is OP for melee group as it is a smart heal, and totems are a blessing. "no pun intended"
