^ It's actually extremely hard to increase movement speed with masteries now. The most worthwhile MS increase is 21 points into utility, after all.

I like MS quints on a large number of champions, so this is a fine change, but I still feel boots and pots will be picked all the time, if only because it let's you dodge skillshots like before with greater ease and because of how awesome pots are.
