My reasoning was that soul energy doesn't passively increase, whereas mana would. You can also buy mana and mana regeneration, whereas you cannot buy soul energy.

You are correct, it doesn't make much difference. But given it's his resource, and not his passive, it doesn't overly make any difference to his kit... it just affects how he plays.

Yes, I could just make it so he doesn't benefit from mana regeneration...
