Weapon Normalization

[MongoJerry]

The only reason I can think of to use a big slow 2-handed weapon is when using abilities that have cooldowns. Since those are never your primary attacks, it doesn't seem worthwhile to prioritize those.

What about Arcane Power efficiency for a Wizard? The skill costs the same per cast whether you're using a fast weapon or a slow high damage weapon. So, why not use as big and slow of a weapon as possible to improve the damage/AP ratio?
