The stats to damage range "Calculate" button does nothing for me, other parts seem to work ok. (also you have a "-" instead of division symbol)
Also Hero/Paladin have skills that use 2 separate primary stat multipliers, it'd be nice if you could work that in somehow, so I don't have to use 2 column to get average damage and then add, multiply and divide to get the real average.
I'd also like to see more of the boxes become dropdowns, eg. there are only so many primary stat multipliers, you could just put them all in there and save people some lookup time.
