So I'm level 18, just spent the last few hours doing Guildleves at Dry Bone and just wanted to know if I'm doing anything wrong...

Basically, progression is going immensely slow. The mobs in the Guildleves net me around 30exp each, and at the end I get 600-700exp. Then once I'm done with the four, I have to go back to Ul'dah and register another four and do it all over again. Surely there must be a better way to level up.

I don't ever recall FFXI being this bad, despite it being known as a grind fest back in the day.
