I think astarion stats are ok, it's not optimal but I think it matches his character.
I disagree, I preferred it when he had bad intelligence instead of strength, because lets be honest, hes undeniably a fop and a bit of a dumb bitch at times. If they did it so you could class him into arcane trickster, he's still not going to be a good one even with the INT boost, both his spell dc and caster bonuses are in the toilet, just not quite as much as they were.
And before anyone tries to argue "but he speaks too well to have below 10 INT!" That's really not how it works. 9-11 INT is the average range for people, and I really wouldn't expect a player to start going "hurr durr" with their character unless they something like 6 INT or below.
