CLASS MOUNTS
You can reward an armored version of the characteristic flying mount of the race you are using, the armor style of the mount should match the armor and weapon style I mentioned before.
OR
I don't know how customizable the mounts will be, but also you can just reward the armor style and the armor style recipe (for crafting) that can be used for all our mounts, plus some accessories like saddle bags or mount chair, there are at least 3 rewards there for CLASS RANKS.
All the other ranks can be filled with at Least 10 CLASS TITLES.
