No, these followers are not trying to be anything. They are pack mules and meat shields.
Well yes, seeing them as puppets obviously will create discontent, because they arent. See them as virtual people. Actually followers are very well implemented in Skyrim, by far the best i have seen yet. They walk independently to towns or players, no more cheesy teleports(ok still some). Their AI and pathfinding, aside from that they dont jump, is quite well done, and variative depending from class, which is totally not obvious. Some will use dual weapons, some will keep distance, and some will be close. Also i have yet to see them failing finding me. Sure there are situations, where he/she is lost, but in Skyrim you are sure he is actually walking to the player/town as an independent
entity and not just players extension. In other games losing sight a sure sign that the follower is bugged and lost completely. In other words dont worry about his performance he is quite capable. Ofc, player's possible/usual overpowerness does not leave much room for them, unless gimping yourself.
