it *seems* that people are generalizing xp gain based on battle classes. yes, if you can find a good party the instant you log on without waiting for people to join, do it for 4-5 hours everyday, then maybe you can rank up very fast. however, most of the time, i'm waiting for an hour for people to join a party, then grind for an hour before people start getting bored or hungry or sleepy. i also supplement my grind parties with several leves that net me less than half an hour of xp parties. in that instance, you don't level up very fast. i would imagine that i am not in the minority with my style of xping.

aside from battle class, you have to take into account the xp for DoH and DoL classes. they don't get xp chains or pl's. how is increasing the xp curve good for crafters/gatherers? focusing on one narrow scope of battle class xp is not a terribly comprehensive way to suggest a balanced xp system for the entire game.
