It would be nice if the ARR hunting bills had exp just like the HW and SB counterparts.

But I'm just curious. Why not do some command missions on your alt dps instead of waiting on a dungeon queue?

No queue, no penalty if you have to leave early, keep all the loot, and the monsters have an extra 60% exp added on (to the base exp, not shown as a %) when doing it as a command mission. Sure the AI is dumb, but at least it's consistently and predictably dumb. It's pretty much 1.5 level for 20 minutes (30 if your AI is still low on its tactics levels) from 30 until 50.
