So, once revisiting I have witnessed reformation of Metapotence. Before it was something similar to Omnipotence but separate on its own. Now this is an essential aspect of True Omnipotence: capabilities and description were changed as well as new users added. Actually, I really like these changes and saying it's “Omnipotence in Action” is a nice way to put it. That also resolves simplification of Metapotence:
Omnipotence is a philosophical concept of being God of monotheistic doctrine. That's why the omnipotent beings are above everything, can defy absolute everything. They possess the greatest freedom and inconceivable Indestructability. They are the Rulers that no else rule over, Creators nobody created, Destroyers that no one destroys. They are eternal, so they don't have any beginning nor conclusion, their existence is absolute transcendent over everything and they are boundless and almighty in all senses and aspects.
Metapotence, on the other hand, is the action aspect of Omnipotence. That means Omnipotence alone is versatile state of being no one can truly understand, while when the omnipotent acts in some way, this is Metapotence. So, MP is now power to do anything, while Omnipotence is state of being. Now Metapotence is completely obtainable Omnipotence, as it can do everything Omnipotence can while without those things that make the utter one unachievable. Now I brilliantly understand its simplification and everything is put in just right order.
Also, I see the tendancy for granting various powers essentially connected with Omnipotence the rank of its aspect. Currently, Absolute Transcendence and Metapotence are its aspects, so what would be afterwards? Would Eternal Existence be its eternity aspect and Omniarch its lordship aspect? Actually, I think this is also a great idea to make Omniarch an aspect as well.
