Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey guys, I'm going to start playing on the PvP server. The only WoW I played was MoP private server, never player vanilla. I want to know what's more fun to level and in PvP, warrior or rogue, and which faction is currently more fun on the PvP server? Also, are city raids a thing here?

Not too sure which faction is most fun (Still lower level and only played on Alliance), but Rogue would probably be more fun, you can gank more effectively and also avoid ganks easier. Just remember, this game is nothing like MoP, it is much harder, you have to pay attention at all times. Mobs can, and will, kill you at any time.
