I would love ritual spells to be in the game. It would definitely be an improvement of BG3's spellslot system outside combats.
About identify...
I love how it works in Solasta/BG1-2 for my immersion in the setting but is it really interresting ?
Magical item found = Click ritual/Identify = discover his properties.
Am I ok with this ? Definitely yes.
That's how things works in DnD and everything that would increase the poor immersion of BG3 in it's setting/world would be welcome.
But is that fun and interresting ? Not really IMO.
I agree, the rituals need to be in the game, they are part of D&D.
I also agree with your comment on Solasta and how they do it. They seemed to have captured the essence of D&D better than Larian at this point, even just using the SRD. I am baffled on the fact that BG3 is supposed to be a D&D based game with full licensing from WotC, yet seems to miss several core elements of D&D.
