An Eder-type companion would be great. He was so un-special and it was nice.
Yeah he was special in being so aggressively normal, something this game really lacks. Apart from the PC, who seems remarkably shallow compared to each and every companion who could rightfully be the protagonist of his own game.
But this is a Larian game, if you are not playing an Origin Character, you are playing the game wrong. You would think having a custom character name show up as Tav would tell you everything Larian wants you to know about your character. The PC is not the hero of this story, we are the sidekick unless your choose to be a protagonists, i.e. an Origin Character.
