Just be aware you will be subject to constant ganking by level 60s as soon as you enter contested zones. I don't mean occasional "lol you got me" ganks. I'm referring to constant corpse camping, graveyard camping, flight master and other NPC killing, etc. I played on a PVP server in vanilla, so speaking from experience the ganking is orders of magnitude worse here than in vanilla retail.
You might be okay to grind is isolated areas, but don't expect to complete many quests after level 25 or so.
