I like the diverse melee weapons in this mod, but it feels a bit strange that there are some weapons which do not rely on the melee ability of the wielder. Probably this is a design choice to diversify the arsenal more to have an extra characteristic besides damage amount, damage type, accuracy, strength bonus, weight, size, price.
Its just a small thing, but I think it would be better if all melee weapons should depend on the skill. In comparison, there are also no ranged weapons which do not rely on accuracy.
