It's actually also metioned before (I think it was you, Anara) that we also consider the subclasses from BG2 when creating a character in the original BG. That makes it even harder, for instance (also mentioned previously) the Kensai, who really does not have any plausible background when raised in Candlekeep.
What bothers me even more is that a book has been written which is about a man fulfilling the destiny of a protagonist in the BG series. In this case, it's a human, male fighter (if I recall correctly) and that's annoying because it seems that there is one "true" protagonist.
As for the druid... I'm still not satisfied. I think there should be some kind of signs in the game that the protagonist could be a druid, just a tiny little indication.
And after all, the game certainly favours good-aligned characters when considering both Gorions alignment and Imoen's. And Candlekeep is such an innocent little society, to think that an extremely evil and violent character could be raised here, surrounded by Gorion's friends, the Harpers?
Anyway, I have given it a great deal of thought... But some things just don't fit with the story.
Or what?
