For one thing sometimes they attack on Cautious (not always) which really annoys me cause I lose all chances of further sneak criticals by waiting out until hidden.
The next thing that bothers me is in closed spaces, like vaults and the like. I get detected while I shoot from some vantage point and get swarmed. Now the logical course of action to me is to position myself in such a way as to cover the entrance to where I am and start shooting once enemies step through. But can my companions sit still and play it out? Nooooo. They run head first so fast that sometimes I don't even know which way they took.
I like ED-Es perk, even with high PER you can't compete with him, but he just annoys me to no end when I see him charging. It's gotten to the point, where on my second play through I just don't use companions anymore except just enough to do their quest if it's not too much hassle.
So is there a way, a console command, a mod or something that just makes companions passive? As in stick to my side, never run off, even if it means they don't attack anymore, I don't mind that much.
