Ultimate Showdown of Ultimate Destiny - MPQ Edition

I wasn't positive if this topic should be in the Events, Characters, or General subforum; my apologies if I chose poorly.That said:

Earlier this morning I was thinking about just how long the list of nerfed characters was getting, and it occurred to me that it would be a lot of fun to have an event in which all of them were playable with their original array of powers. I doubt that that would be feasible from a development perspective, but I'm really curious as to what the results would be - both in terms of general playability and in terms of which characters and teams would end up dominating. I half wonder if we wouldn't find things to be surprisingly balanced. Thoughts?
