as i can see here about your runes .. Your going for full Ap with some heath ... can only say that´s awesome to have alot of ap .. but you dont need the heath rune´s becouse if you know how to kite just a little you can easyly kite can heal .. but the problem you dont have so much mana to play with .. that´s why i allways play with a clarity or i play with mana per level runes .. so you can keep kiteing and wait for your mana. but btw awesome Song :P nice one

One more thing I forgot to add! Don't be afraid to buy health and mana potions along the way if you have some extra money to spend. They will help you to stay in lane more and do better. Also, sell Dorans Ring whenever you need the extra money, but sometime after the Rageblade, so that you can benefit from it as much as possible.
