Whilst I love that wizards have the feature to add spells to their spellbook by spending money much like in 5th Edition D&D, I don't understand why this has been extended to every spell from every class. This takes away the uniqueness of spells from other classes and makes little since in terms of lore, as divine magic from the cleric, ranger etc comes from a different source than the arcane magic of the wizard. My two cents is that it should be limited to the 5e Wizard Spell List - otherwise, wizards can become healers and divine buffers which just makes no sense.
Loving the game so far, looking forward to the rest of early access and helping to shape Baldur's Gate 3 going forward!
