They are removing Boot enchants?
Im not sure where they are getting this idea. Boot enchants add a massive strategical advantage, high engage comps are able to use "Captain" enchantment just as easy as mobile based champions are able to use Alacrity. They've never had a major impact on a game to the point of breaking it, but they've always been a major decision point in your late game build.
Its the old saying....
