Hey guys I've finally got back to playing the witcher 3 after a couple months of not playing it. Idk why I didn't I forgot just how amazing this series is. Anyway I am thinking about getting the expansion pass. should I beat the main quest before doing that? I am at the part where you have to meat yennefer in skellige.
