I also totally forgot about. Derp. :|

I think there's value in keeping mana as a resource system on champions, since the system itself is functional and can often succeed at doing its job (i.e. forcing champions to eventually return to base). Making mana champions manaless could risk fostering some much less interesting overall gameplay, such as poke mages hanging back and spamming spells 24/7 without needing to back, or sustain champions using their self-healing without restriction. There are definitely champions who could probably become manaless or have their own resource, but that would be a tiny minority within the mana champion roster.
