I'm not a rage quitter but I'll be honest, the missing companions bother the living hell out of me. Granted my reasons are probably different from most of the people here. I'm a young widow, swtor offered some fun escapism where my characters got to have husbands that were alive in a manner of speaking. Just a game, yes, but it was a nice distraction. I ran my Jedi knight through and lost my Doc, talk about hitting a tender nerve. Yes, alright, I got him back through the terminal, but he's not really back. (I know he isn't super popular, but Aona loves him and misses him.)
My Empire main will not be running through the expansions until I know when and where Vector will return. I've had that toon for five years now and Inari is not gonna lose her bugboy! I've kind of had my fill of losing spouses. Enduring that in real life, in your twenties tends to sour one of the experience in game. Hey, maybe I should throw the young widow card at the devs. Sad thing is, I'm only partially joking, lol. The other sad thing is that it wouldn't get the devs to pull their heads out of their butts.
