Kind of champion concept?
While i have no idea what champ ideas are coming up i ave an idea for a resource bar. what if they made a champ that used mana, (or something else), but had no mana regen and 2 forms. in one form their abilities use mana, while in the other form, using abilities restores mana, therefore to play the champ well you have to balance both forms to not run out of or have to much mana. While i dont know if this would be used i thought maybe make a champ kind of destruction creation based? in destruction you use mana and in creation you make mana?
Just a thought.
