Not only was this egregious, greedy and a slimy thing to do to your player base at a celebration event for 10 years of thriving, it was also devious and manipulative, and I don't mean just the FOMO aspect.
By releasing this bundle the way that you did, and now that people have bought into your manipulative FOMO tactics, you ensured purchases so you have the perfect "excuse" to not create separate bundles or make any major changes without upsetting one group or the other.
Great play DE, you are crafty I will give you that...
