Just wait till you get to Bozja then, large parts of it are incompletable solo or without a decent sized party, and it's pretty much empty on a few data centers.
If you think 50 minutes for Ivalice is bad wait till you have to spend days waiting for Castrum to pop with enough people to do the mechanics, or spend days/weeks queueing for Delibrum waiting for enough to complete it, or for people to leave their Z3 farming in Zadnor for Dalriada to get off the ground.

They've needed something for these underpopulated side instances for a while but so far not a lot of solutions.
