If we get a Dragon class in WoW, I'd be perfectly happy with them having a Dragoon-flavored Melee spec. I made one myself, but anything that plays even remotely similar to something like Dragoon would be fun and snappy and full of dragon flavor.
Definitely need the other specs to be ranged DPS and healer, we have enough Melee I know, but yeah. Lances are cool as hell.
