I'm on the fence when it comes to this topic. I mainly PvE, with a splash of PvP rarely (about as often as I play other video games). Both sides have their points, but this whole ban-stick topic makes me wonder what stops Blizzard from doing the same to multiboxing PvP or multiboxing WoW in general. Sure, they currently say its ok... but they can reverse it (Forum QQ = Blizzard action?).

As far as Arena goes, I imagine a lot of folks who got hit with the ban stick are just canceling their account and waiting for newer games (Warham, Conan, etc). I know if my 70's got their gear stripped to nothing and suspended by Blizz I'd shut down all my accounts and move on.
