For me the major plothole in DOS2 was how the female mage I played in Divine Divinity turned into "Lucian." I'd like them to respect full series lore to the extent that it doesn't contradict itself and also to be up front about whether our character is actually predefined. Letting us play the character we want to, only to find out later that the "real" Bhaalspawn was Abdel Adrian just doesn't feel good.
