First of all the companion wheel doesn't even work considering it seems all of your companion's AI are set to "do whatever I want to do regardless of player input." I'm always opening it back up to make boone re-equip his rifle because for some reason he just has to have that machete ready to go.
Or the fact that even though i have the set to passive they still immediately run and attack the first enemy they see. The worst offender of this is ED-E who will run half way across the map to attack rad scorpions while I'm sneaking past a group of deathclaws.
They have no sense of self preservation. Veronica will run into a group of sentries and get killed before she even gets to them, again while she is set to passive mode. Even the enemy AI has a better sense of self preservation than the companions
Has anyone else gotten the glitch where Lily repeats the line "don't worry deary, grandma knows how to stay quiet" every ten seconds while sneaking? yeah that is a fun one.
The worst part is when THEY JUST DISAPPEAR.
It's kinda sad that the best way to use a companion is put them in your group and tell them to wait in your house so you can still have their perk...
