I think it was wrong to provide so many guild leves available. Even if you're not casual, they are the best source of SP, and as a result players feel they need to do them every reset. If you don't get lucky on leve links or you're not gaming the system. these leves sometimes take 1-2 hours to complete. So with my group we play usually from 6-10pm, takes us about 30 mins to get all ready and to travel to our spot, then another 1-2 hours to do the leves not including breaks (Food/WC/Behest). Usually at the end, we're either to tired to do anything else or we already stopped early to go to bed.

Leveling from 1-40 wasn't so bad, as the areas changed and the monsters changed. Getting to level 33 was refreshing, as we started to fight more interesting monsters. However, we are in the 40s now still doing the same leves (After jumping from regions and trying all the leves, we found Gridania to be, by far, the most enjoyable).

If I were to make one suggestion....

Increase the Guild leve cooldown to a WEEKLY cooldown, and make world monsters much better to SP on. Obviously fix the SP first, but save the Guild leves for more special encounters... for example: Instead of the lame kill 12 monsters, make it one difficult monster (help players learn new tactics by encountering more challenging monsters) that rewards a significant amount of SP at the end.
