I'm shocked that they finally took action on this. For me, arenas have been totally UN-FUN. On my priest, instagibbed by the other team and play in the arena had no bearing on my favorite spec, holy. I wasn't about to respec every week into a spec I don't like and was not familiar with. I always had fun playing BG's as holy though. On my lock the differential in resilience when I started arena (at the end of S2) was enough to make it unfun and when S3 hit it was even worse, even going into BG's started to suck hard until I finally got some nice pieces. I always wondered how it would be fair for all the cheaters to have the best gear and the rest of don't so I'm glad they are attempting to fix it even though some people will be caught up in it that shouldn't be. After a while I just stopped arena'ing altogether, I might even give arenas a try again on my lock after this wave of bans.
