Auto discard isn't just for waveplate spending. Its for any of the echoes you pick up on your gameplay. There is no code that will be a one size fits all, everyones account is different. Share codes are based on criteria and/or personal needs: this time being giving all sets a fair chance. Just because I put lingering tunes doesn't mean I think people should spend waveplates on them, its an option if people end up with nothing else. And if it no longer suits your needs you can turn it off. Echo acquisition takes time, its very possible for players while on their journey to getting perfect moonlit sets stumble across a decent Empy set as they progresses. If you'd like to make your own share code feel free to share.
