% Movespeed is based on base movespeed. With them and the 4/4 mastery you end up with 6.5%, which amounts to ~319 movespeed. It basically reverts the last nerf to her movespeed and passive, however you will usually have 7 less AD than the other carry (it's about 10% more AD for reference). So, it's a tradeoff to either make her early game "not-SO-bad", or have much needed survivability/chasing power due to moving faster.
