I think this is just gonna be how it's gonna go in the future, tbh. We only got 2 ults in stormblood and endwalker, where in EW it was just because it was an overdue fight from shadowbringers. I wouldn't be surprised to just see 1 ult per expac now, where they did 2 for SB and tried to do another 2 for SHB, but they found out it was too much to properly do+balance and will just go forward with 1 from now on. And if we're limited to 1 ult per expac, then we only really get to see 1 ult demonstrating each expac, unless they want to be constantly falling further and further behind. So I think Omega was all we're gonna get for SB.

Kinda sucks if that's the case, but oh well. I was still at one point holding out for my dream ult (kefka+triad), but without them doing 3 ults per expac I don't think we're ever gonna get random/surprising ones like that.
