Especially him being a vampire spawn despite not having any vampiric attributes...
Um, what about his teeth? Red eyes? Super pale skin and a bite mark on his neck?
And thats all what you think a vampire is?
Not only has Larian removed the traditional weaknesses of vampires, running water, sunlight, they also completely ignore that he is undead. Doesn't eat, doesn't sleep, doesn't feel anything. And in D&D vampires (and vampire spawn) also means having regeneration, ect.
Astarion maybe has 10% of all attributes of a vampire spawn.
