I have a lvl 70 warlock on a PVE realm (Nazgrel) on WOW. Looking for a PVP realm in US. Any recommendations? World of Warcraft, PVP US realm recommendations for level 70 warlock

You can't transfer from PVE to PVP realms, so you'd have to start your character all over again. If you're willing to start over, I'd recommend going to a new realm so you're more evenly geared.
