Well, I agree with Anubis that it does have room for improvment. It isn't about mages having enough MP really...or not having enough RR. If you compare NIN 2hr to other ones it doesn't seem as useful. A lot of other 2 hours can turn the battle around when things get bad. Ninja's (The one's I played with) don't die. The ninja's I play with only die when it is a mass wipe...then the 2hr is kind of useless.

I agree it is useful (If they die a lot...) to be able to get rid of weakness. But if you don't die..then well, it is useless.
