I got my Plumed Barding the other day and noticed that it clashes with most other pieces. As I was admiring it I realized that the colors and crystal accents could go well with Crystal Brave stuff and thought it would be nice to have Crystal Brave Barding.

As for how to possibly get it.... Please don't make it the next level of veteran reward! Maybe as part of a difficult new sidequest in an upcoming patch or the expansion?
