By "flaws" I mean rearing, bucking, running away from you in field, trying to invade the space, hard to bridle, hard to catch, one-person horse, etc. Because if it comes to emergency or the situation when you are forced to sell the horse you'll be in big trouble. So yes, I'd want my horses to be as "flaw-less" as possible for my own sake and the sake of people who have to deal with them.
