So after playing almost a full year almost full time as a SMN, I've decided I'd like to try out NIN. I've tried messing around with leveling a few other classes before, but never really felt like I enjoyed them, and kind of gave up with them. So far (as of only level 13 at the time of this post) I've really enjoyed ROG and would really like to push to make NIN my first alternate level 50 job.

So, to my question:

When leveling an alternate job, what tends to be the most effective way to level? To date, I've been doing Leve after Leve in order to level ROG, to be able to take part in the class quests as they become available. I figure once I hit 16, I'll be able to break into the world of Dungeon grinding. I'm also every now and then working on my hunting log. So what I'd like to know is, should I just continue in this way, unlocking NIN along the way, or is there a more effective way to level a second job?

Any help is appreciated as always!
