In Shadowlands, for a variety of reasons, many players build the wrong legendary or simply choose the wrong secondary stats, will there possibly be a refund or disenchant system for Legendary items to reduce the cost of replacing one?
That's an interesting question. We don't have any current plans along those lines right now, but it's something that we can look at, providing some way of either changing your secondary stats or getting a partial refund. The thing we'd want to be careful to avoid is a world where it feels too easy to make one legendary for one situation (PvE), then disenchant or change it to a different one to go PvP, and you don't really feel like you ever need to build a collection. But I agree that making a mistake there feels like it could be frustrating, and we should do more.
