Happens all the time with the DLC unfortunately. I've been hoping for 2 years for a sale on the Nioh season pass, especially since the complete edition keeps getting sales
They punish you if you buy a game early now. You get the shaft when it comes to season passes, dlc, pre-order dlc.
That's why I don't buy games till the GOTY, Complete ect edition. Usually you get the game and season pass, all pre-order dlc for like 70% off while the people who bought the game early get left holding a empty paper bag with no discounts.
The trade off is I end up being about 6 months to year behind gaming on everyone else.. Hard to beat Assassin's Creed Odyssey Gold for $33 5 months after release vs buying a standard retail copy early.
