I don't know, I find it really unfair that my seniors have to be stuck with their (honestly) old default armors, while the new knights get to use newer sets. As a small-time fix to the CE economy (somewhat related to this topic), why don't you guys add a feature where you pay 10-20k~ crowns to get a default makeover? It would serve as a popular crown-sink, and a temporary fix might help you guys buy time.
If the other players don't like this idea, why not stop being pessimistic and help out to improve the it?
