If you do /pvp in Ironforge when the plague hits, you won't get infected.
Thx - didn't know that. Thank goodness there aren't usually any Horde around the Alliance capital cities, or I wouldn't fancy doing this 8^).
I have a couple characters on a PVP server as well, and really get tired of getting murdered (by Alliance in that case) in contested territories all the time when I'm in the middle of trying to mind my own business and do a quest. My son thinks the PVP servers are great, probably because he has a nasty L60 Undead Rogue that most players don't challenge, but I've come to find the PVP servers to be a PITA. Personal preference. Fighting other characters all the time is not my cup of tea.
