Overall an ok guide, a few things though.

1)Many spelling mistakes through out the guide, such as ''choises''

2)Rushing Blood Thirster isn't the best anymore after patch 4.10 as it no longer gives extra AD, in other words BT got nerfed and the shield it gives is over hyped. It is much better to rush Infinity Edge with a few Doran's Blades for sustain

3)Little mistake on saying how Sona is not so good, but in the description you say she is good, just a bit weird.

4)Taking barrier instead of heal is questionable, many do prefer heal because it allows you to kite with the speed boost and gives the adc an ability to help another team mate.

5) Greater Seal of Armor got nerfed, so they are also not very good anymore, a better option is a mixture of Greater Seal of Armor with Greater Seal of Health

6)Mistake on masteries saying how you go 20/9/0, should be 21/9/0

7)On summoner spells section it is a lot neater to use Flash instead of an icon, to do that just type [ [ability name]] with out the space.

8)On skill sequence you just said what the spells do, you need to explain when and how to use these spells to make it a guide.

9)Lastly have a few more champ match ups, cover all the adcs and supports in the game

So yeah, overall a good guide with a lot to work on, good luck :)
