I agree that we need inmprovement in this area. Even NWN2's quick cast menu would be an upgrade.
NWN2 spell menu was the best I have ever seen.
If it is used as the highten spell meta magic for sorcerers (cast spell at higher spell level), it can be used for every char in BG3.
regarding solasta: I have not played it yet, but I will at some point.
Looking at the screenshots the UI is much better than BG3.
Both games are turn based party based RPG based on DnD 5E, so it makes absolutely sense to look at the other game.
I would say that Solasta is more similar to BG3 than any other game out there and if we compare BG3 to something, than this one.
Some rules are different, but thats OK because its still different games from different devs.
Solasta EA is on sale on steam at the moment.
