I love Gain XP for the gil, unity points, raising the rank of the unity to which I belong, etc. But yesterday, well, I did 8 or so Wildkeepers and 3 Delves! :) Cool, but by the time we were done with everything, I just couldn't get up the energy to do Gain XP. :(
Final Fantasy XI really is the never ending game! So there is always tomorrow and next week to help out in the unity rankings!
