This is a fun build that will take enemies by surprise and gives you a lot of cc to get kills with. It also gives your a lot of team fight pressure with your ult. Your passive scaling with AD means that you can also get some good damage off with it, when normally it is just an extra thing to do in your combo. When laning, use your Q to poke enemies off wave so you and your support can go in and collect cs, or use it to get the cs if the enemies have good sustain.
