Hello,
I have played this update quite a bit and would like to suggest to either remove enchantment power from gems all together (as the title suggests) or put limits on it like on the elemental gems. Some like the low health are just too easy too fulfill and make it so you man not even want to use any other infusion if you can easily double the effects.
Instead maybe make a new unique ring that increases the enchantment power of all armor pieces by a certain % but with a big drawback as well, maybe it increases your roll weight by one entire level or something bigger.
