Companions are just such liabilities, I really dislike the quests that force them on you. Just did the companions quests and I am not sure if it's a bug but they seemed really low level and "collapsed" in about 1 hit while sneaking really badly. My character is mostly sneak oriented and I don't do very well toe to toe, so they were a real hindrance. Still loving the game though. I still have the main quest to do, have been putting it off and just enjoying the rest of the game. I think the bards college is the last of the guilds for me to do and I still have a bunch of quests to do for houses. I also plan to work my smithing and enchanting at some point as I'm still wearing quest armour and I think crafted armour with enchants would be better.
