Suggestion: When dye kits are awarded by a Birthday Gift it would be great to disable or identify kits that have already been completed for an account. This would prevent a duplicate selection that cannot even be sold since the dyes are account bound. It's also not something the player can check in-game since opened dyes aren't grouped by specific kit source in the Hero menu. The only other research option would be on a wiki page if that exists, but it would be better to have an in-game solution. Given the annual nature of the Birthday Gifts, it's frustrating to have wasted the opportunity for a new dye.
