Players should have the ability to remove non-story required companions such as HK-51 or Treek. I would really love nothing more in this game then to no longer have the horrid furball on my ship. I realize there is no true advantage to removing unessential companions, but after KotFE and the massive increase to roster size of potential companions and still having plenty to max on crew skills, I would really prefer to remove some that do not contribute story-wise. A simple option to dismiss them from the party so they may continue their adventures on their own would suffice or even the ability to send a few on a suicide mission that is known upfront so that their departure could potentially have some type of reward for their sacrifice.
