Their builds are tied into their stories, yes. The team believes that altering them has a negative impact on immersion
Please explain how 14/13/19/9/10/15 TSS Val with EWP: Bastard Sword ties into her Story. Or should we just look at the 9 Int and say "well that explains everything".
or if you are adamant that you need this and it won't affect your experience, I believe there are mods that let you accomplish that.
While I can certainly use Mods, there are still many People that play either on Console or just struggle to use Mods. Would it be to much to ask to put the Option for full Respecs into the Game together with the Warning that the Developers will be disappointed if you use it? (Similiar to the Unfair Warning)
You see, between having so much stuff we'd still love to improve about the game, a rather limited demand for this, availibility of mods for majority of the players and extremely limited resources for things like these, this would be very low on priority list, even if we wanted to do it. Sadly, as a developer team, you always have to choose what you can afford to put your effort into, can't have it all.
