Yeah but half of those will function as boss fights, and some of the others as groups of unique special monsters, which is essentially a form of a boss fight. I do like the Roman outpost idea though, chance to find some legionnaire armour and tower shields.
Please by all means I like all the suggestions in the threads, more bosses, more special loot. But I feel like with a little thought the devs can create missions that go beyond, “Go here, kill X, come back”. Like for the orc unification, there can be an objective to assault a fortress that constantly spams orc young and warriors/berserkers from time to time, but you have to light X huts on fire than go to the edge of the map and retreat.
