you already earn XP on crafting and fight mission with mobs you kill or item you craft.
on bonus, it gives you fame and dappers/elyps.
as Moniq said, they are timed for respawn (some are up once a day, some in a few hours), I don't see the point to use them as grinding method...even fighting herbis is faster :)
I would prefer having more encyclopedies (theses are far from complete or bug free) or sage-like missions (there's only 4 extra-bugged ones atm). theses ones makes you travel a lot (and grind), may give you some nice bonus at the end, and get you into the Ryzom story.
