So I think for Wizards, the best weapon setup is at either extreme, either super slow, or super fast. I just got this 1.55/sec 1Hand and it's so awesome. I burn though all my AP shooting Arcane Orbs in like 5 seconds, then spend the next few seconds slashing like crazy with Spectral Blade (Siphoning), which along with Astral Presence and Power Hungry brings my AP to max really quickly, then I spam all my Orbs again.
Hmm, if I replaced Power Hungry with Prodigy, I could get so much AP with Spectral Blade, and I wouldn't have to rely on health orbs.
