Hard to choose

Honestly, can’t remind of the last time i actually used a companion in fallout 4

I started doing that when I got the cannibalism perk

I assigned every other Companion either farming or defense jobs at The Castle (I left Strong to wander aimlessly around The Castle grounds) because the first perk I unlocked was Lone Wanderer and I've spent the better part of my playthrough trying to finish Cait and Hancock's queslines.
