And that kind of arbitrary-ness is what I dislike.
welcome to role playing. RP is not about min-max-ing. its about playing a role. and a role (its portray) might be not be perfect. if you missed out something b/c of your role played not-perfectness play the game again portraying another role.
(...) but keep in mind this is a FREEFORM class system. Or classless system. You have no character roleplaying/behavior/alignment other than what you decide to do at any given time.
and here is your mistake. classless is not role playing is not min-max-ing. those 3 terms are not directly related to each other.
classless does give you the opportunity to shape your character as you like, but it does not necessarily prevent your character from the consequences of a certain behaviour or choice.
only thing you can complain about is that Larian kind of hard coded the consequences of a certain behaviour (like always getting +1 for a trait X b/c you chose dialog option 2 in a certain dialog). But that is a never ending story because there will always be those who do not agree that a certain behaviour yields a certain outcome.
