Not to go point by point, and though I think you're still reaching for some of them, I'll give you this: Death or not, I can understand if you've felt there's been a de-escalation of stakes in regards to straight out character danger, because to that I can agree.
I wanna round it up, because I don't want us to start going in circles. My main argument is that there's many other ways to have an interesting conflict that lets the characters grow other than them dying or not, and it's a bit tiring to keep going back to the same "they should just die" plot argument. There can be so much more. I can't believe I'm gonna say this, but aveyond had a bit of a point about making characters disagree with each other. Triangle Strategy has a rather awesome party, and they often disagree in their values a morals, and we didn't have much of that with our XIV party. I do believe the Scions have had nice growth moments built on all sorts of conflicts, though I think by now we've exhausted much of what can be done with them, and why I'd be really happy to have a new cast in 7.0
