Well I can level MRD with you. I've never even unlocked it.
Also working on a couple alts who don't have anything leveled yet. Took an alt from one to forty in about three days. The system certainly isn't perfect but leveling is an "experience" that all RPGs have. With the armory bonus it's laughably easy to get a job to fifty now.

And before you ask is it necessary personally I think so, in order to learn your job. Some people don't work well with just throwing a bunch of skills at them and go "yeah figure this out".
