so I will just respond to the question in the title.
To answer your question, absolutely not. The companion system is fantastic in SWTOR. Could it be improved? Always.
This post was never to doubt the system in place (How Affection works, Crew Skills) and stuff. This post was, as later clarified, about the question if Bioware should've given us more then the generic companions we got. A way to customize our crew with people our character would spend time with. Not people he'd despise.
Please, if you don't read a post, then don't answer it. That's just a bull**** thing to do, especially if you want to complain about a letter.
