Stop changing the power.
The power was changed to fit accordingly with the other sub-powers of Meta Power Manipulation, it makes no sense being superior to the power it is a sub-power of or it's equivalents.
Also, a power having Omnipotent users DOES NOT make the power in question Omnipotent, it just means....it has omnipotent users. An Omnipotent being using Water Manipulation doesn't make Water Manipulation an Omnipotent power.
Honestly it just feels like you put only omnipotent users in the know users just for the sake of it doing so, since almost none of them have used this power. So please, do not change it back.
