"as ms quint works with percentage, the less base ms you have, the less it gives you ms... since vayne has (ironically) the lowest ms in the game, those quints can be somewhat useless (I did some math here... 300+(300*0.045)=313.5 ms, which is not that geart) She could use better quints."

The movespeed quints make up for mobility for a short ranged carry with already low movespeed. They also synergize well with her passive (where she gains 30 movespeed bringing her base up to 330) and ultimate (as the ultimate triple's her passive). They continue to be further noticed as teh game goes on into late game and people have literally no hope of running from you. AD quints help with last hitting and aren't noticed at all late game. Armor Pen quints might be noticed but she already has the tank busting true damage. The movespeed quints (to me) make up for a glaring weakness after her nerfs.
