U know riot is out of touch with a champs identity when they recommend a support build as a primary

Meanwhile YI, Tritana, and Soraka were reworked so riot could keep them out of the places where they didn't belong, and how many times was eve, rengar, and nidalee reworked? One too many.
midlane with the change they made? The AP is pretty shitty yes but the 2g per 10s and 15g per hit (max 45g in 30s) will pay for the item itself so it can be sold later as it'll help you obtain full build faster. CDR because why not, and 150% mana regen seems useful. It also has the twin shadows active now which is pretty useful with the current state of vision, plus slows = easy skill shots
