The problem is that people who own both Blood&Titanium and Legacy of the Ancient cannot buy Living Weapons pack, even if they were willing to pay for YOE upgrade. Adding Living Weapons to Season Pass wouldn’t quite address the issue, as it still leaves out customers who bought DLCs 1&2 seperately.
Perhaps Snashot should just make Living weapons free for everyone? Afterall, you either own it, or you cant buy it. And for those few who own vanilla PP only, it is not a big givaway, as they still need to buy YOE addon, to get access to DLCs 1&2.
As @Valygar has written:
As I am googling it, the price of the upgrade is £11.99. I also don’t know why the price on screen shot is displayed in $. Whatever it is, it’s wrong currency and wrong price, unless you try some shenanigans with region pricing and Epic falls for it on store page, but not on checkout. If you are not happy with the price, I would suggest waiting for a sale - especially once later DLCs are available for purchase, the upgrade is likely to be discounted at some point in the near future.
