this is more of a general feedback post, but here goes
can think of two reasons why they'd bring back items:
a) the team is incredibly understaffed with untrained members who can't create a set quota of items, hats, whatever in time so management decides to bring back older items to compensate.
b) upper management is trying to suck out as much money as they can out of a sinking ship. essentially coaxing players into believing certain items won't ever come back, creating a rush to buy said items, and then bringing them back a few years later to gain even more profit and create the same physiological effect in player's heads.
give the game two years - it will lose all its previously loyal players due to ****ty policies like this. competing games have and will take over - this is inevitable. graal is an old game. now it's just a matter of wisely spending resources and perhaps paying staff instead of relying on volunteers that, for the most part, create sub par content that can in no way compete/hold its ground against other games.
adding on to that - what's with all the censorship graal has that regard other games? it's so petty. can't think of a single other company that does this. its parrarel to the social climate and censorship that occurred in the USSR, lol.
stop ruining the game more than it has already been ruined. be original and think creatively when making hats. if it comes to it, remake stuff that has been poorly made in the past and resell the new version.
perhaps from now on there can be a section or label, as eugene suggested, that indicates a hat is limited/special edition.
it is not hard to think of new ideas.
a unified style is desperately needed with the newer updates, many games nowadays require staff to match a certain style - why can't graal? it gives the artist experience with certain art styles. while unique styles are good, it heavily damages the aesthetic and 'magic' of the updates that they used to have.
hopefully graal 3d provides something new and exciting, although my hopes aren't high
