Good points.
Yep. It will be up to us to play alignment but I want the decisions to matter in some manner. Viconia was in most of my parties and by the end of the game she had shifted her alignment from neutral evil to neutral. Sarevok was in nearly all of my ToB parties and he started Chaotic Evil and became Chaotic Good. And, if you were playing with the semi official ascension mod that really mattered in the final battle because evil Sarevok would turn on you.
It was fun. I felt like decisions I was making mattered in some way. So I'm totally fine with party of mixed alignments -- Korgan and Mazzy had some good interactions in BG2. So I do wonder what will happen to shadowheart if she accepts help from a Selunite . . .
And if it doesn't matter then someone has messed up
