PVE or PVP? If PVE, I think you can also consider Saurfang. Its a rather new server compared to the older ones which has its advantages. Being new server, people are rather friendly and forgiving to new players starting out. Its gonna be tough to find elitist idiots here (considering most of them either transferred out or got heckled out).

Both alliance and horde side have guilds that have completed all content which is rather surprising since most people equate strict elitism = progression. If you want to progress but in a friendly server do give saurfang a try.

Hope you find the place you are looking for. Good luck.
