I think some folks are forgetting that Dragon Age is, first and foremost, a game which has certain rules built into it. no matter how immersive the story is, no matter how epic the scope of the characters or dialogue or penguin launchers or whatever, there is still a game there. Most players will naturally bring in non-immersive elements, such as dice rolls or attributes or follower tactics or inventory, and justify them with in-game and in-setting reasons for their existence. A good example of this, which was brought up in this very thread, is follower inventory.
Some players will see this as the party discussing among themselves and agreeing that Isabela should wear such-and-such armour because it's better protection than her brigandine tutu (hypothetical) and besides, Varric needs the spiked pauldrons of enhanced Bianca synergy (also hypothetical). Other players treat inventory management as purely metagaming and don't ascribe any in-game interaction to it at all.
There is nothing wrong with either way of playing the game. it is purely subjective and, in a single-player game, irrelevant to anyone else's interpretation of the system. If you expect your followers to "follower your commander's orders and wear what you tell them," then great. If, on the other hand, you feel the followers are "distinctive characters in their own right with their own opinions on what to wear," great. Regardless of which system is actually implemented in DA2, players can determine for themselves how to reconcile the system with the setting. Or not. Whatever they wish.
So please, let's stop assuming that one's way of playing the game or dealing with inventory is better or worse than any other. As long as it works within the context of the game as a whole, I think most players won't be too disappointed.
