Deep dungeons seem like an alt-job leveling superhighway! Are they?

[LaylaTsarra]

I level using roulettes. I don't personally do any of the deep dungeons. I'm also not in a rush to level everything. Don't get me wrong I've leveled quite a few alts with all their roles and am now really just focusing on my main. She is an omni and I'm slowly starting to climb her mountain. I have friends who have rushed to straight 80's and now have nothing much to do and are bored. Just a thought.

I suspect the dungeons are really good for leveling starting roles that begin at level 1.
