About Sivir
I really don't understand this:
Sivir has low range, low health and low damage (after nerf Q) at early game. So why do I should to pick her, when I can pick Lucian? More damage, more health.
Sivir is a very dangerous pick because she become strong at level 6, but is very difficult with her without die one time or losing a lot of cs.
I think she need more health in early game.
