I also tend to the slightly too easy crowd.
I have the unique perspective of having 2 rosters, one semi-hc roster (Titan cleared in 8 days, currently after transition on alex ultimate) and a very very casual one with Real Life friends (so no real discrimination on skill level) that raid only ONCE per week.

The difficulty of the raids tiers of Kefka / Omega felt right to me.
We were usually able to clear the raiding content in a span of 5 month (usually just not enough to have 8 weapons for the next tier), now we cleared Titan week 9 with this schedule and are left with basically no content to do, while we will try ultimate once for fun, its obviously not something our casual group can handle (we know we will never meet enrage of the liquid even if we got there).

My guess would be that we miss a 5th boss, because in essence during all of Stormblood it was like having 5 boss with the final one being 2 bosses in the same tier. Now that they stopped doing that (and its good to get some change don't get me wrong) I was kinda hoping for a 5th boss harder than titan, with maybe only limited rewards like the Mount to give us a bridge to the next content, or prepare more ambitious groups to Ultimates.
