Yeah I very much prefer spell points to spell slots.
Spell points DO buff casters but it isn't like Larian hasn't completely *clears throat* "played around" with other balance changes far more daring; bonus action disengage, delicious potato > healing word and including backstab(facing) and height advantage consequences which again, actual variant rules in 5E.
Spell points is a clear optional rule that enhances the experience for certain players and I'd hope to see it as an option in the custom difficulty choices eventually. Otherwise *sigh* hate to have to say it but there's always mods...
