Your point is very well taken!

I've dug into the files and looked at gameplay but found something odd -- certain skills benefit from Strength/primary attributes but others do not! For example, comparing Battering Ram (50% weapon damage), Whirlwind (90% weapon damage), Crippling Blow (130% weapon damage), and Flurry (70% weapon damage), the numbers in game are quite different.

Crippling Blow seems to deal much more damage than expected, which could be explained if it received a 50% boost from high Strength, causing it to deal (1.3 * 1.5) = 195% weapon damage. Likewise, Flurry does more than the expected 70% weapon damage per strike, explainable only if it was dealing (0.7 * 1.5) = 105% weapon damage per strike. This can be seen when you compare the tooltip damage to your sheet damage as seen on the character sheet. I don't notice this issue with Battering Ram of Whirlwind, however.

The phenomenon I'm describing can be seen in this Man at Arms Bully Test video, where the tooltip and actual damage dealt by Crippling Blow and Flurry vastly outstrips what it should be. For example, Flurry shouldn't be doing more damage per strike than Whirlwind, which you can see highlighted in the tooltips in question.

Do you have any ideas?
