Leves should be removed or atleast downplayed for overall gameplay?

[Renshi]

well ya i know the title is misleading but what im saying is lol :| that leves should still be here but they should be less rewarding behest should be more often and random *like ff11 campagin :|* and other things should be added in and they all give exp so the casual gamer can go do those while ppl :| like me :| could party and do thos eon the side while the casual can do the little things whille partying on the side when they ahve time

Prefacing that I've not understood 90% of that, what do you mean by "Other things should be added"? More so, what do you think they should add?
