Note:
Any character can pick the Ritual Caster feat and learn any two ritual spells from the list of: Disguise Self, Enhance Leap, Find Familiar, Longstrider, Speak with Animals, Speak with Dead.
I personally find that the smaller spell selection makes sorcerers shine as specialized casters, while wizards are very great generalists. So I do like having both of them in my party [...]
Why yes thats how it was in BG1+BG2 (BG1 only since the EEs).
You had the Wizard (called Mage) for spells like Sleep that would later be useless, and the Sorcerer for spells that would stay useful (though wasting a few spellslots on lower tiers wasnt so awful; as long as you kept having Magic Missle picked you could pick any four slotwasters of spell level 1 spells just fine, it wouldnt matter in the long run).
But we have a four peeps group now, so thats really of the past.
