I expect there will be arcane gears for this expansion.
I hope it would be weapon for all classes, since the latest arcane weapon is lv36 staff, let alone lv26 dagger and lv31 maul.
There are already so many mythic weapons showing up on the market, we need an brand new arcane weapon for each class.

(It would be perfect if old arcane weapon can be upgraded via some hard quest and solid gold, coz some proc and visual image of them are so awesome which I don't want it disappear from end game.)
