Yeah so that's the calculation I was trying to do. If I get the on sale version now, then the upgrade to deluxe, how much does that save. So you kind of did the for me, thanks!
The other wrinkle is I played a lot of WoA on PlayStation. I have the deluxe edition on there plus some of the dlc but not all. Do I need to own package parity before cross progression will work? Haven't looked into that yet.
