An unwritten rule for homebrew is that if you give characters a benefit that significantly benefits one class, then other classes need to be compensated. Non-Spellcasting classes all get abilities that increase their DPS as enemies have a higher than average HP pool. Wizards have nothing to accommodate for that fact and do not benefit from monsters AC being lowered. The spell pool is a lot smaller, not including all the spells in the game, and say chromatic orb; they give that to the sorcerer? That's a wizard spell! As it's a PC game, creative freedom for spell use is highly diminished, thus further weakening what a wizard can do. If anything, wizards need some compensation if the other classes are receiving them. I'm honestly disappointed Larian is not sticking to the rules and is essentially changing this into a different game.
ehm....chromatic orb is an arcane spell available to both sorcerers and wizards in both 5e phb and in BG3, it hasn't been a wizard only spell since Ad&d. In fact, in 4e it was a sorc only attack and had some similarities with how it's portrayed in BG3.
I do agree with you that Larians constant home brewing messes up the balance between the classes but if we want them to stick to the rules, we should also be on the same page which rules those are.
