It can get ridiculous.

Spent an hour and a half in line for the low level dungeon daily roulette as a MNK.

Spent one second on Tam Tar NM as a Tank. Literally, one second. One second for one specific dungeon, an hour and a half and I would have taken any one of countless dungeons. It's nuts, but expected.

I'm used to Zerg FATE leveling from the 2.0 days. I just get in the DF (leveling my ARC right now) and FATE/Leve until it pops.
