well thats true but serana was very fleshed out for a follower, dawnguard and dragonborne added probably a dozen followers, not all of them were complex, most were not but a few were more advanced like serana, and the skall chick also the wizards apprentice wasn't a simple follower, so but i don't expect a lot from each dlc, probably 1 or 2 from far harbor and there will prob be another large expansion and probably another follower or 2 there, they all don't need to be complex but i doubt it will be as numerous as skyrim, there's not a bad selection in the base game, a dozen or so followers, skyrim has about 40 for the base game.
