The question was answered, but I'm bored and will offer a bit of advice.
The best use for evades is from monsters with carrier attacks. If you're trying to get away or avoid dying in a really bad spot from something swinging paralysis/vertigo/death/etc., an evade is a life saver. It allows you to keep your dodges for the really bad things that you may get hit with later. I've heard a lot of people say they aren't fans of the skill, but like any skill in this game its use is situational. Rogues are all about being ready for anything and everything.
