I want to specify what I mean, as I know that the concept of bringing back the CMPs is a topic not up for discussion as the pinned post says. I completely understand the reasoning why (eg. Glitch pets/Glitch pet colors)
I don't have any issue with this.
However, with that being the case, why not just remove the CMPs from the collections that have them? /genq
If they can't be added to the Golden Vintage Bag (which let's be honest is most people's most likely way to get retired items to complete certain collections, if not buying them from people who get them from GVBs) then it makes most basic Creatu collections effectively impossible to complete.
Especially for new players.
Even for an older player like myself, it's honestly Incredibly frustrating to have completed some of the "harder" collections, but not being able to finish "Kayoki" for example because of an item that was retired (I believe, though my sense of time is bad) over a decade ago that is never being brought back and is completely out of circulation.
