Ashe is a stun on your ADC with some mild poke damage. That, as far as solo queue is concerned, is dead meat in any teamfight. Ashe gets countered by any sort of mobile assassin. Rengar, who is really damn popular, just gets fed off of Ashe so easily it isn't even funny.

That said, I'd drop MF one tier, make Corki his own S tier and up Sivir and Kalista one tier each. Sivir, I find, is really underrated as an ADC. Her midgame teamfights are extremely strong. Kalista literally counters any non mobile champion and basically most of the skillshot champions in the game by her passive alone. She also offers MASSIVE objective control, almost Cho Gath level of it.
