No, I agree. The spawn ending is toothachingly sweet, especially in the new epilogue. Even spawn Astarion needs to keep his "bite" IMO and he comes off as a bit too nice at times.
But I really love the Ascended epilogue and got exactly what I wanted out of it. My evil ex-Durge just reveled in the evil couple stuff, still seeing the talks with Astarion as a constant game and ignoring his low-key threats ("I'm always watching"). I loved that I could talk with God Gale about the possibility of Ascension. *evil snicker*
And with my goodish ex-Durge who just wanted to give all the power to Astarion for safety reasons but who had buyer's remorse there was the whole freedom dialogue complete with Astarion's gaslighting. Damn, what a gut punch!
Oh yeah, there are some sentences where I've definitely gone "okay that's going a bit too far with his goodness". Overall I still think Spawn Astarion is the one that changes Astarion's attitude the least between the two routes but they def overdid it here and there. I didn't love Astarion's epilogues either way, tbh (I don't think Spawn was overly "good" in this case though, but I much prefer his friendship version, as cute as the hug is) There are things I like here and there of course, esp some hidden lines (like with Origin Ascended Gale) but overall I found it all bland and with less content than the other characters, which is uncommon for Astarion but maybe deserved after all the favoritism he's gotten throughout the rest of the game lol. At least I can be happy knowing I correctly predicted what his good and bad ending would look like back in EA, lol. I thought his good ending would have him become a chaotic/morally questionable monster hunter/adventurer and that his bad ending would be him becoming a Lord and turning Tav into a spawn. I didn't predict the Ascendancy aspect but close enough! (Now remembering how his writer said the original concept for him was "Medieval Deadpool" and how that becomes kind of true for his spawn ending...)
