these are the origin characters, they are that for a reason, they're going to be playable, for a reason. the point is that there is much, much more to them all than meets the eye, hence them being the 'origin' characters. larian said we're getting more companions, who we will likely spend less time with than the original 5, they can save all the normality (aka boringness) for them. & using the word 'obviously' in regards to certain companions (including the only one i even like at all) is the first problem: nothing is completely obvious about them & first impressions are rarely even close to accurate for ANY of them. they do all have secrets, that's why they are specially set aside as these first 5 & why they will be playable, so you can eventually figure out about all the things you were wrong about when judging them by first impressions alone.
& as for finding out secrets too soon (like the vampire thing) remember, we have a long, long, long time before we get the whole game, & if they were all 'normal' with no layers & no shades of grey to their personalities, they would be painfully boring to play with for however long we'll be waiting on the next content update IMO
