Retired items are more valuable. Not only in terms of money but getting something exclusive giving us this sweet sweet dopamine and I love it! Either by getting item while it's able to buy/grind or buying this item from other players after grinding and saving for it.
I understand most people just want to get everything for free but it is wrong. You should be rewarded for taking part in something when it's up. Like in this case being rewarded for giving your precious time to grind for this new items. Right here, right now.
I would love some items to be retired permanently, maybe this 4 entirely new companions? Only few items, but still: some of them. BUT! Some form of soft retirement would be good compromise for both sides. Collectors like me, who loves exclusivite will get some very rare items but others will still be able to get them at some point.
EDIT I found out some items indeed will soft-retire so this thread has no sense anymore.
