I think that tonight I'm going to start a 4-Ninja group and just do the trash of the highest dungeon everyone can queue for and see if that works better than other methods. My ROG is 27 (I think) right now so I'll be trying to get queued for toto-rak I think.

I'll just have to evaluate to see if it is better than FATE grinding or leves.

By the ways leves are pretty decent if you are quick about them.
