Companions hold me back :dry:
I just hate feeling like I have to babysit them all the time. If they die I feel bad, so I usually end up just either keep them out of combat or wasting healing items on them. No thank you.
I pretty much agree with you, I always tried to keep my companions alive in Oblivion so they felt like more of a burden than a help in most cases. In higher levels they'd get owned by a dremora pretty quickly anyway.
I mean this isn't Dragon Age, nor is it Mass Effect, companions in the Elder Scrolls will probably never be that integrated into the system to where they are as a big part of game-play.
Rather than a companions following you around in the field, a relationship npc in town, like a husband wife type character or even just a friend with some back story would be better I think. Rather than being forced to baby sit some character who is helplessly trying to follow you through the woods and getting hung up as he tries to find a way to you only slowing your own progress down...
