You know riot messed up when

An ADC is viable without needing A SINGLE CRIT ITEM. Remember those buffs to kalista riot? They were totally fucking unecessary. She can't be "VIABLE" because assuming her kit, she will always be either OP or UP. People used to cry about ashe permaslow. She can only "permaslow" ( league of mobility, permaslow my ass) a single person. Meanwhile kalista can kite a whole team while doing stupid damage without crit items.
