I was actually planning on leveling a MCH soon. They look really cool, and I like their animations. So the posts in this thread are helpful.

As for MNK, I leveled a PGL up to 15 or so, then immediately ditched it to switch to ROG so I could unlock NIN.

I can’t speak for others, but wanting a ninja might have something to do with why you don’t see many monks. I mean, monks are cool and all, but ninjas are freaking ninjas!
