Mechanic Concept: Mana Decay
Right, this isn't quite a champion concept, but an idea for a possible gameplay mechanic. How does mana decay, as in a progressive loss of mana, sound for a champion mechanic?
Starting a game, the champion would have 0 mana. From this point, auto attacking will grant mana for use of abilities, which would then begin to decay either immediately or a short time after leaving combat. During combat, however, the decay would be inactive.
Thoughts?
