God I hope not. I had more than enough of arena by the end of TBC, season 5 made me laugh my butt right out of arenas for good. Really depressing to play a Ret Pally since launch, and be non viable in pvp the majority of the time, then WOTLK patch drops and overnight your spec is turned into an absolute faceroll FOTM behemoth, not to mention lol Icytouch DK's. But that is a tale for another day.
Cultivating an immunity to rebuttal is not a substitute for being correct.
