I'm not sure what the abilities of classes are in DnD but I notice that Wizards and Sorceror have pretty much the same abilities minutes a select few. I also feel that Wizards should not be the only one that can learn spells. I think that is unfair to Warlocks, Clerics and Sorcerors. In my opinion, the game doesn't have to be 100% DnD just based on it is fine. DnD is based on existing lore, they just tweak it for their own. So, Larian can also do the same for a video game.
Wizards can learn many spells through scrolls and they have more spellslots but they have to long rest to recover them.
Sorcerer have less spells and spellslots but they have metamagic and they can recover spellslots with their sorcery points.
Warlock have less spells and less spellslots but their spellslots are up again after a short rest.
Cleric knows all spells available and can pick those they wants between every long rest.
Long rest and short rest makes the balance between spellcasters. Long and short rests does not work as they should in BG3. Dnd is not the problem. The resting mechanic in BG3 is.
