Ahh Grasshopper, I appreciat your view and disagree.
While currently there is only one research track and all critters in in thral under the same sphere set, it is not a simple 'anomoly'. There is a substantial difference in sharing a common mana pool and research effort than in having an isolated uber-being dropping bombs from afar.
The fact is that heros will acend to what ever level of absurdity the map limits allow no matter what the nature of the Wizard. Having a body to move about makes it personal and you could still have evolution to that god like state, thus satisfying both views. Options of coporial body only, evolution and mystical presence could be made in the editor.
(by the way, what is HoMM?)
Actually, if you have a little time, I'd be interested in what you think of IDEAS I-IV.
My basic principle is that options, features and evolution are very important aspects of this kind of game and the more the better. If we eliminate the corporial leader, we lose a whole track of evolution for the character and evolutionary choices that could change the nature of the game in play.
I really want to see some guy with bare feet and a club ascend to god-hood, an arrival that doesn't end the game but opens up more possibilities.
Drop an email sometime and we can compare some notes.
