As a player that enjoys raiding and PvP equally I would love it if there was either dual specc or less cost on respeccing, so you can actually enjoy both to full potential.
I am looking at raiding 3-4 days a week, and between raids pretty much all I am going to do is PvP (given i sometimes need to farm for upcoming raids). With the current price of respeccing its just not viable to be able to enjoy your character to the fullest if you want to play both parts
