I have to admit, even as a gamer who doesn't typically tend towards PvP combat, the recent news that Blizzard was removing the arena team requirement from participation has piqued my interest. I've played a bit of arena before, with a small team of friends, but we were never serious about it -- or particularly good at it -- and our mutually busy schedules didn't give us much time to play together. But now, participating in an arena battle looks like it will be as simple as queuing up for a battleground or dungeon run.
On the plus side, that makes it easier for newbies (like me) to give the system a try. And, who knows? Perhaps arenas will become my new favorite thing. And on the down side, it might mean arenas will be flooded with newbies like me, who will be a nuisance to everyone (possibly including ourselves). But dangerous flood of newbies are not, will the patch 5.4 changes be drawing you into the arenas?
