I meant "awesome" in a relative sense! What I was trying to say was that you'd almost need to fulltime a Spell Reduction set to benefit, and you'd be better off fulltiming evasion instead. On further reflection, you could probably just macro your gear in while casting, but as I understand it, a NIN's inventory is almost always bursting at the seems, which makes carrying even more gear somewhat unattractive.

But I can't really talk! My NIN is 33 at the moment and I don't plan on taking it past 40.
