Precisely. I have never seen a single example of the AI casting this spell when it would do any good and many times when it will be harmful.

As Strages Sanctus mentioned, Quickness should be the very first spell the AI tries to cast, when going down its list of available spells, unless the spell is already in effect or scripted.
