Boots of swiftness change for slower champions

The new boots should give you a ghost effect when you activate it.

Except the cooldown increases if you use another mobility skill or receive one.

Mobility as in - dash teleport bloodboil etc

The reason for this is there are alot of champions in "noob" tier simply because they aren't faster than other champions.

Sion - cool stun, slow champion - not very good Darius - really strong, also too slow for higher play Kog'maw, Urgot, Ashe, cool interesting mechanics etc, too slow. (Remember when almost every ADC ran GHOST FLASH) Nautilaus . . I mean he has a hook to wall mechanic. . but it's not "broken" lol

So instead of "balancing" every champion that isn't in the god tier of picks. . why not just introduce a boot upgrade to make them better?
