Now that there are more and more raptor skins every month I believe it can start to get difficult to get a specific one you want, even through getting eggs in bulk. I went through 150~ eggs last month and only managed to get a single Krampus raptor, and I just have to think about how difficult it is for newer players to collect skins.
So I propose a blacklist, after you collect a certain amount of a specific raptor skin, you can then blacklist it to prevent it from clogging up the current pool. The original colors shouldn’t be able to be blacklisted to keep at least a bit of randomness, or make it so that only one, two or three skins can be blacklisted depending on how many special ones are out that month
