I meant critical chance, not damage. I also thought about making it depend on the weapon type but;
A) Not every weapon in a melee category scales with STR.
B) It's probably not fair for guns/etc to get to triple dip on damage/critical/hit from one stat if the other weapon classes can't double dip.

Not every weapon scales off of SKI, but they all use SKI to hit. My point being is that strength could still reasonably cause more critical damage, via reasoning that the brute force when hitting the right spot can be terribly effective.

You still need LUC to hit and crit. Having only SKI and no LUC will cause problems for one's build. To do good damage with a gun, you often need to go Magic Gunner, and thus also build WIL. In addition, many guns have terrible scaling and have gotten terrible damage levels since the bugfix. The ones that don't have terrible scaling have other problems, such as doing Earth damage (which isn't terrible, but it isn't helping them any).
