I have some suggestions to make:
Don't put 30 points into offence, you need a 21/9/0 or 21/0/9.
Use BBCoding to make
the items/abilities labeled and prettier.
Why are you getting Hextech Gunblade? You only have 2 abilities that do damage, and you only need one activatable slow if you have boots.
Keep the boot. Why are you selling boots? You need chase, and boots are really efficient. If your build is really finished, then you can buy Zephyr.
