I think I have found the problem in regards to the Dragonmaw+Human being borked.
In Buffed_DPS Sheet, there is an identical error in the MH Crit Racial and OH Crit Racial fields:
[top]IF(Gear!B11
"Human",IF(Gear!D13="2h Mace",1%,IF(Gear!D13="2h Sword",1%,IF(Gear!D13="Sword",1%,
IF(Gear!D13="Mace",22,0)))),0)+IF(Gear!B11="Orc",IF(Gear!D13="2h Axe",1%,IF(Gear!D13="Axe",1%,0)),0)
As you can see in the bolded part, mace is currently giving 2200% bonus crit. So, changing the "22" (I assume this was for crit rating) in the formulae back to 1% fixes the problem.
EDIT:
P.S.: I see that the current version of the spreadsheet is giving expertise for Weapon Mastery. Since it is -2% dodge now, is it equivalent to edit the expertise given to 8 (assuming 2 points) instead?
