Caitlyn is a AD Carry champion, She is one of the lot of ranges champions who have an good default attack damage score.

She can slow, stun and his ulti cannot fail (only if u shot a another ennemy champion ^^)

Also my Idea, Caitlyn is really one of the best AD Carrys.

Most of the lol fans are looking for Caitlyn LoL champion build to clear levels and win the game with one shot and kill.
