I think what he forgot was that they want to change poisons anyway.

If you're not applying a damage poison with your offhand, and you have a few stabs that apply base damage of both weapons, why would you want a slow weapon?

Realistically they should make the damage based off the DPS average over the time period rather than the base damage. So a slow weapon and fast weapon do the same damage on instant attacks.


Though really, I guess at some point they may as well remove weapon speed if it's not going to really matter anyway?

Well the poison (as far as I can tell) does flat damage per level, which is why instant poison coats the speedy off-hand. If there was no off-hand poison damage, the slower/stronger weapon would up total damage in %damage abilities. Using DPS average would cause major problems when haste is applied, since the average damage keeps going up. Upkeep on Slice and Dice would turn those abilities into ridiculously hard-hitting nukes. Heroism phases would do the same. Abilities have to be based off the base damage % to keep them in balance. Actually, off-hand utility will mean rogues want the slowest dagger possible (Assassin/Subtlety) or even slower agility weapons (Combat) so that 1 of 3 rogues competes with Shaman. Except agility swords. Those are all Combat.
