Well, wands just suck outright as far as damage goes, so it doesn't matter anyway.
DW axes is easily the highest damage in the game. It doesn't need an extra 25-50%. Dual wands meanwhile barely even outdamage an unskilled staff shot at 5/5 dw 5/5 wand, and I'm sure you know by now that staff damage is pretty low to begin with.
The one and only reason to use dual wands is the stat/attribute bonuses. They roll all the same attribute bonuses a staff can, so wielding 2 of them effectively doubles that. You can't put a tormented soul on them, but I doubt you want str/dex on your wizard anyway.
