As long as Riot is aping ideas from a certain other game...
Let's talk Jinx. The attack speed she can build up is pretty insane. My suggestion: She must remain stationary, or move very slowly, while channeling a rapid-fire line AoE that she can steer. The first champion it hits is struck as though by a basic attack and this is where the attack speed comes through. Being able to point and click lightning-fast autos that early in the game with no real drawback is getting to be a bit much.
