16 guildleves would take a while to get through sure. However, whats the point of having a hard cap on the amount of available leve per day? Especially with the 1.18 changes? It serves more a hindrance than anything.

Its available content that is tightly restricted, but FFXIV desperately needs.

What if the reset timer was on a per leve basis. lets say there are 12 total rank 30 leves in Limsa Lominsa. You pick up 3, complete those 3, now those aren't available again for 36 hours (current reset) but you still have 9 leves left at the adventures guild. As well as all the R30 leves in Grid and Ul'dah.

More available content, but not repeatable for an extended time.
And you have content available for multiple ranked classes. since you have r1 r10 r20 r30 r40 leves all available on their own timers.

Just a thought.

But the more we have available the better for everyone. It keeps us in game with something to do for extended periods of time, when it a slow day.
