It's by far the best movement skill in the game, it needs a drawback or every other movement gem would be obsolete.

The drawback is not being able to proc fortify with it which is huge.
Instead of it having a cooldown, adjust its cast time/range/whatever so players have to invest into cast speed (even movement speed perhaps?) to be able to use it efficiently. This way it'll be more reliable and more fun to use.
