Wizards being a great dip is a bit of a red herring to a discussion - the larger issue to me is how much Sorcerers got buffed and Wizards... not. Together with flexibility always less important in a CRPG than in tabletop, I think Sorcerer will always be better by a considerable margin.
I still loved the original BG 1 + BG 2 without Sorcerers and where you didn't get any spell picks at level up. All spells had to be learned from scrolls, and it was a great way to make treasure exciting for casters.
Also agreed that the game does not need to be balanced around multiplayer guilds. It's clearly intended to be either played single-player or with friends. It's not an MmoRPG or something like that. If you want to play like that go ahead, but I think Larian could spent their working hours better than to balance for it.
Agree. Learning spells whild level up is indeed completly stupid as well as paying for learning new spells. If you are in the middle of nowhere and you wanna learn a spell you have to spend money. Who will get the money? This is just a further DnD BS.
