Last night leveling my monk, and this morning leveling it again, I'm getting ganked by high level flyers at the rate of once every 10 minutes (usually concentrated in pockets of misery). I've played since vanilla on a high-pop PvP server where there was a lot of opposite faction, but leveling has never been this terrible. So I decided to shell out the $25 for a server transfer.
Is there anything I should know about PvE servers. I've heard terms like "flagging", but I don't know what that is or how it happens. Besides flagging (for PvP I assume?), are there any differences to know about?
