I hope Square doesn't keep deeming certain content unnecessary

The thing is. Critical engagement bosses are really no different than eureka bosses.

Yes they are. Yoshi-P has said they are different than fate bosses. He explained that Skirmishes could be done in the open world, but that Critical Engagements are different and involves the sort of work that would go into a dungeon boss. That changes a lot, really, because that means they redistributed resources that would go into making dungeon mechanics and did it in Bozja and Zadnor.
