Debate--bring back limited time items

I have been playing since the middle of the Christmas event so I got some of the items from that and everything from the events since. What I think would be a good idea would be at each event bring back all of the previous event items as well as new ones. Before you are able to get any of the new items you have to have already got all of the originally released items. That way the players who already went through an event will be getting new items and the players new to the event will have to work through the older ones before getting to the new items. Episode tie ins I think should stay as the 1 time thing as the whole purpose of them is really just to promote the upcoming episode.
