So I'm very excited about vanilla, regardless of how it shapes up. I don't see myself being a dedicated raider (at least not for long periods of time), but I do intend to play quite a bit. I'm thinking my best bet will be holy priest, since I think that will maximize my chances of filling in for established groups.
Thoughts? Although I have many years of experience raiding as a tank, I really don't think it's a viable choice for someone who doesn't intend to be committed to a long-term raiding schedule.
