Dual Wield

[Seredoc]

The formula is the following(I just spent a yesterday locating all the info)
Mainhand normal ratio is (damage*2 + damage bonus)/delay with damage bonus being (level - 25)/3 and offhand being ((lvl + dual wield skill) / 500) * (dmg *2) / delay.

Using a level 50 with 200 dw skill: Jade mace as primary (9 * 2 + 8)/18 = 1.44(higher is better). AC as primary (15 * 2 + 8)/25 = 2.11

As secondary now, opening math is the same ((50 + 200)/500) = .5 so moving on. Jade mace .5 * (9 * 2)(duh) = 9 , 9 / 18 = .5 and now AC .5 * ( 15 * 2)(again duh) = 15, 15 / 25 = .6

Really generic example but all in all the AC is the better weapon in both categories, also to determine overall dmg ratio you add the two. AC main jade off is a 2.61, Jade main AC off is 1.94. Put your AC in your main hand.
