personally I am against including ultimate (絶) in regular development schedule of FF14. It takes so much effort of dev while so little of the players can enjoy it.
1 ultimate per expansion at most.
I love dev to bring more vivid details to eorzea such as better graphics, more gears, more variant battles and less bugs/model clippings.
That being said, I did enjoy all the ultimates so far especially TEA(with a full JP team except me who are so nice that I will probably never forget in my life).
