Legit build is legit ^

Please tell me you don't legit buy ad carry items as a support in real games. This is troll right?

No item explanation and lack of colour/pictures.

Also, build is not so supportlike while your title begs the differ.

Sorry buddy but your build doesn't exactly agree with the term "support". You say that he needs good farm to win a lane, but your a support? In the current meta the AD carry gets all the farm while you protect him and make sure he is safe from junglers and the enemy carry. You might want to revise on this one a bit as the build is all over the place. Supports don't exactly get a Bloodthirster and an Infinity Edge.

This build has promise but you really need to decide what role your build fits in the game. This to me seems more like a solo top build if you take away the sightstone, but even then..

Anyway, good luck with your guide.

Edit: By the way your masteries are all over the place too, but you have some good, basic information on his spells, try to go more into detail :)
