Greetings!
You know, Rounser, I think that I entirely agree with you!

There are many reasons that I can think of why it is unnecessary to stat up gods. As you mentioned, "Avatars" can be quite useful, and appropriate to stat up for a variety of circumstances. However, to what point is there in even "defining" gods? Gods are *Gods* To show how ridiculous that sounds, look at this:
Assuming it is reasonably possible for a mortal--a human, say,--to reach a 30 strength. Isn't it strange that a human, a mortal, no matter how powerful, can approach within a mathematical quantification the strength of a God? Gods are theoretically entirely beyond the scope and comprehension of mortals. Gods are so far beyond the comprehension of puny, limited, finite-seeing, handicapped mortal minds that there isn't any comparrison.
By defining gods thusly, one puts a mortal, limited form upon them. By expressing this limitation, of whatever number, then the god in question can be therefore defeated in detail by some strategem or concert of actions. That distinct possibility--of befalling a god--just seems counter-intuitive, you know?
Again, avatars are fine, but why is it really necessary to stat up gods? You know, it's funny. I have been running a Rolemaster campaign for several years, and even though there are characters up to 70, 80, 90th level, and immensely powerful, they never *once* physically encountered a God! That's in several years of real-time of playing! I never once had the necessity to even know the stats of a god. It was entirely unnecessary. Plainly put--if a god had any such kind of limitations, it would be beyond the characters ability to know it, and even if they somehow did, the god would still, even with whatever kind of limitations that a *god* would have, still possess the ability to utterly annihilate the entire character party in a blink of an eye--no die roll needed, saves are all failed, *snap*--they're done. Time to roll up new characters! That never happened, as I said, but the point being, what real use are *stats* for gods? How are they relevant?
