The part I hate is getting to 15 to begin doing dungeons - I actually don't mind running dungeons too much just because each run is a level until around 25-30, and by that level you start getting new toys with most classes. I at least have 20% xp gain, and might just go crazy farming for the shoulders and chests I don't have, just so everyone gains 45% xp, but that means not boxing my team up for a bit. Bleh - I wish early dungeons gave a handful of JP!
