No Auto-Attacks?
How about a new champion who hasnt got auto-attacks? The champions Q could be a point and click type ability that has a short cooldown and low mana cost. The champion could be a mage who hasnt got high scales on abilities but short cooldowns. But thats just my idea so i dont know if it would work.
Sorry for bad english...
