Arena of Annihilation is part of normal rotation. I didn't even realise the quest was in there though, I thought you had to get it from just outside Temple of the White Tiger, so thanks for that.
With crafting, its worth knowing that the crafted 450 PvP gear is no worse than normal 450 gear. Thank god PvP Power and PvP Res doesn't count towards stat budget.
Very good episode though, very useful!
