I like that at least a few people out there also find the trope of the reluctant vampire pretty frustrating.
Of course he should Ascend! hehe
That's the Fin to the vampire film I always want, but never get, usually hehe. Instead it always has to be a moralizing thing that comports with all the usual rules, so we invariably get saddled with a watered down Louis archetype instead of a full bodied Lestat. As if Vampires stories were for the people who don't want to eat, or get eaten? Come now! I mean right Lol
The best is the Vampire who just rolls with it and finds their way into their own, refines their taste to focus on eating the right sort, say dining on worse villains maybe. Recovering humanity is boring cause we already know what that looks like. The worst Astarion ending would probably be something like "Yay he's cured of his vampirism. So happy that he no longer has to worry about it at all!" Least they didn't do that.
Of course many things will push the player towards not becoming, so they get stuck outside, never invited in for the fun part.
This is my favorite vampire movie...
Here's one just with the tune, for the slow build...
I mean sure it isn't a vampire movie, but it's totally a vampire movie! And that music is playing in my head pretty the whole time after Ascension, like once he's got his vampire smile on!
I had the same reaction as the OP, that maybe I'd misread some of these other companions all along, so next time just ignored them and acquiesced hehe
