Well, either ReplicaX has the right of it, or you truly have flown off the handle here; either way the debate has lost its appeal to me.
If you're serious though; the items are already available in the game by playing the game. If you really enjoy this game at all, I doubt you'd honestly ask that non-seasonal/limited items be removed from the game proper and placed on the Mogstation. Now you're just throwing a fit because you feel that if the game won't treat gear the way you want it to, then no one should have it via in-game means.
