Farsight Totem: Mid Laners Will Rule The Vision Game This Season.

This little trinket on a Mid Laner can provide such a huge amount of vision throughout the course of a game and you never even have to leave mid lane to do it. You can place one per minute and have an unlimited number on the map at any given time. All mid laners should grab this at level 9(For FREE!!!) and just pop one out on cooldown. Downsides being that they are one shot, visible, the animation can give them away, they cannot be teleported to and a Lee Sin can't jump to them. But even if they last for a few seconds they are worth their one minute cooldown for the amount of info they can provide.
