When I played Vanilla I was a Holy Paladin (By choice, not because it was a requirement). Over the years though, my preference has shifted to Rogue. Not because of situations, just because I found I love that play-style a lot more. When I play Vanilla, it will definitely be from a Rogues perspective.
Before anyone says "All they did is heal and spam buffs on 40 people", I'm not really talking about raids. Just in general.
