I think survival mode should do something with the companions. On the normal mode, I just send whoever I am with into the fight and let them distract everyone till they are sitting there. Knowing they can't die is almost an exploit. It should have them die during a fight and then re-spawn at Sanctuary or something.
Or do what Skyrim did with most of them. Permadeath for that playthrough.
Personally I don't mind the companions being set as essential. I end up "killing" them myself half the time because the idiots run right into your line of fire. But. like you said though, they make good distractions. Im hoping that once the creation kit is released, someone can do something about their AI.

That perk... "lone survivor"? Is that it? Next few levels I'll put into that so I don't need a companion.
Lone Wanderer actually. It gives you bonuses for being solo. And believe it or not, I've never taken it. And if I recall correctly, Dogmeat doesn't count against you while using that perk since the game doesn't consider him a companion.
