I wish they had stayed with the original concept of being able to kill companions and customizing companion roles via a "kit". I would have been soo happy to have Vette as my healer and shoved Quinn out the nearest airlock.
This. This, this, this, this.
I humbly BEG AND PLEAD that the next "HK" either be a new healer companion or a means to "teach" a companion a new role.
And then, please, let me put Quinn in a new spot on my ship. Right behind the door labeled "Airlock."
