I personally don't think mutation needs any negative penalty because the fact that it takes the enchantment slot is already a very large reason and it already increases the weight of the weapon. It's a very niche use for a build as the popular enchantments are usually bloodhunt, reaper, divine, avalon, rampaging, and so on.

That is the biggest thing... The enchantment slot, there is hardly a benefit once you lose the enchantment slot. Like Reaper...+5 Power.
