Because every choice is permanent, you can't ever really know what would have happened if you'd taken another route and let it play out. That uncertainty plays to the benefit of the company providing the customer service (BW). We're always concessioning that we may have made a mistake. Because who can know, right?
I'm a fairly low key role-player, but I've had it pointed out to me time and again that you never
role-play your character's story line, because it would result in every Trooper being in the same elite squad, every Bounty Hunter the big life-changing contest, and every Jedi offing the big bad guy that saves the day for everyone.Given that Troopers who so much as mention
Havoc Squad in their stories, artwork, and in-game interactions are treated as outcasts during most role-playing events (at least on the two remaining RP-flagged severs, and in the RP forums) I am completely baffled why you feel that "every choice is permanent" in your interactions with your companions, seeing as every other aspect of the hard-coded story is verboten. Why would a role-player (as specified in your following points) even care what goes down in those conversations, when they have to throw out or heavily modify everything that was said during them to avoid the "My Trooper is married to Jorgen, and everyone elses' Trooper is married to Jorgen, who is clearly in 105,503 places at the same time!" scenario? If you're content to role-play that Jorgen is actually another Cathar - with another story of his own, to avoid the Havoc references - why not role-play that you two never talked about marriage?
