no one knows the muliclass system because its not out yet... define better?
as a paladin you have a small use for charisma but sorcerer doesn't need armour and even when they do its easy for their scales + Dex to outclass most armours so a sorcerer would only get a few weapon option from pally and thats a bad trade
if you want synergy between classes then Bard and sorcerer work much better
