Yes they should do something more with Vaylin

"Please post an example of me " attributing attitudes to people that they didn't say"

You implied that people that wanted something more done with Vaylin ignored that she had done things that hurt people (Oh but those people have families. Yes, we know), when no one ever even implied such a thing. You have stated repeatedly that people who wanted something done with Vaylin wanted to force you to play it when it has been repeatedly said that more choices are better, that you shouldn't have to if you don't want to. This is an unfair discrediting tactic. A pretty sure sign of this is that, when I asked you to point out where anyone said those things, you did not bother to respond.

All you have to do is look at your own thread, where you specifically say "please don't force me to play this", which was never stated to be what anyone wants. And starting that thread is kind of strange itself, since "do nothing with Vaylin" is already the clear intent of the devs (surprise me, Bioware! Make me eat my words!) and I doubt anything is actually going to change that, much as I'd like it.

You've also done the opposite, by asking questions when you're actually responded to posts where those questions are answered, ignoring what people have said. Like you did here.

"Please post an example of "presenting arguments that just don't make any sense at all""

You somehow concluded that being able to get Vaylin back would harm your ability to do group content, because somehow her being used in a team would get you killed as "a ranged" because she's "melee", which is untrue, and that somehow someone that had her with them would not simply trade her out for a more appropriate companion even if it were true. A tactic intended to cause confusion and just generally wasted peoples time and energy on spurious arguments.

These were pointed out at the time. And now you are pretending that you haven't done any of those things and, again, trying to sound "reasonable", like you are the victim of something, another form of bad faith discussion. You keep doing it, and adding new bad faith tactics as you go along, like this one. No one is pretending or posting something that is "in our heads". And now, I've been told this is a pattern of behavior for you, and have every reason to believe it. Let's just say, I've given you every chance. Because, unlike the Outlander, I genuinely have.
