I will not downvote you (just yet... the first downvote wasn't me.) Here's a bit constructive comment for you to work on.

- Your Item build is a mess.. you star with starting item, which is good then suddenly say "everything else" which makes it confusing because of the way it all jumbles up.

- Secondly, you should max Power Transfer over Gravity Field, the scaling is better in terms of damage, Gravity Field is for utility purpose only, it stuns for 1.5 sec at all level.

- Do you really need Archangel's Staff?? any way that's a personal preference so i won't comment on your build but personally, after Augment: Death you should rush Rabadon's Deathcap

- you lack a lot of explanation. Runes, Mastery, Ability usage and Gameplay. the only thing here is "PURCHASE ITEM ORDER" that doesn't really explain reason behind purchasing certain items.

- "FACING OPPONENT" section. hmm... It's a mess.. you said
"Gravity Field, Death Ray, Chaos Storm, Power Transfer, And chase them till they're health drains completely using both DOTs and basic attacks and final Death Ray attack if you're still chasing."

Dude, you just looove to go all out don't you? you don't have enough damage for that since you max out Gravity Field first.

- less color. More Coding pls...
