Then come up with a better system... There is always people complaining about possibleloophles yetthey do nothing to prevent them
They complain about loopholes because gods like to complain and put down other gods. They do nothing to prevent them because there just isn't that great of a demand for the various divine servants you proposed. From what I can tell, people are just looking for a replacement [Angel] trait.
We complain about loopholes because they can and will be abused.
As for the titans suggested...
Champions are not even close to worth the cost, it's just a waste of Essence. All they have is mandatory mortality, and can do stuff. I much prefer Axt's champions.
Demigods, I see nothing really special about them. Divinity isn't really hereditary like that, so they're basically just creating a powerful agent, very slowly.
Gargantuans is something we can create without the system. We already have the innate magic trait and some traits to play with.
Giant Beasts, stat ups and size ups, we already have that.
Legendary Beasts, see Gargantuans.
Spirits, see Gargantuans.
As for the angel trait, I never use it, because I don't like it. Even when I used the trait, I didn't, because I removed the loyalty.
I dislike the loyalty trait, because, in my opinion, it should not even exist. Sure, more loyalty is fine, but absolute loyalty should be impossible.
And Axt is not looking to make great people, he seeks to give them the means of becoming great.
Axt will give the power, but it is up to the people to use it. If they decide to use it against him, that is the price of free will.
So Axt has no interest in the angel trait, because he seeks great people, not loyal slaves. He is a man of firm principles.
