The last thing I find enjoyable is having an arrogant, misogynistic, immoral douchebag following me around. Theran absolutely ruins my character concept and ability to immerse myself in the game, yet it turns out he is the only companion that is at all useful for my build.
My character would never, EVER let this guy on her ship, and if he forced his way on he would be out the airlock and the game would give me light side points for it. He has the most irritating battle phrases, and his cutscene dialogue grates on me. Why would he follow around a Jedi if he gives negative rep when I choose force options in dialogue? Moreover, why would a Jedi let him tag along? It's enough to make me put him away when I turn in quests... and it's enough to make me stop playing my consular shadow, which otherwise is a wonderful class.
So please, either give us a new companion that can heal or give Qyzan (or anyone else) a healing toggle but he loses his tank abilities when it's active.
Because Qyzan is awesome, too bad he is useless to my spec.
