The Brand-New gear sets from the Training Exercises. I realize that there are other pieces of gear that share the same model, but those are restricted to certain classes - only healers can wear the dyeable version of the caster boots, and only BRD/MCH can wear the dyeable version of the DPS chestpiece. While everyone could enjoy them, I especially think it'd be a nice reward if low level players had a good looking set early on in the game that they earned themselves that is also dyeable.
