however, if the removal of every other decent keg in the shop happens so quickly afterwards, then I'm screwed because I already spent most of my ore on the Base Set kegs. Plus, there's also the next expansion to think about, which is probably only a month away. I'm not even free to play; they really shouldn't have their paying customers worrying like this.
I think CDPR will remove old expansion kegs from the shop (and keeps recent expansion kegs) and add neutral kegs to the shop. This might be a bit uncomfortable to players who don't have the most cards from that specific expansion yet. However, players still can acquire cards by opening factions + neutral kegs and does not need to open the expansion kegs. The expansion kegs need to open when a) players have almost entire collections and b) CDPR launch a new set.
Actually, I quite happy that CDPR adds the neutral kegs. New players can complete their collection by factions. Veteran players can complete their neutral cards easier. Elite players can also open neutral kegs to find some premium neutral, too.
