I think you should discuss, in due time, what the cosmetic progression will be. Badges are not enough to keep players engaged, and some form of cosmetic customization tied to levelling or certain achievements should be in the game. The problem though is how will the distribution be. There are so many factions, so many classes and within those classes many get total different armor with improved armor perk. The problem right now is that everyone looks the same and there is no identity of the players. So customization has to be in.
Different badges should showcase some form of achievement of the player. And since we already have grinding badges like 750 wins one, I would love to have badges for (example) 10-20k kills, dismounts, cavalry kills, killing streaks etc. with tiers.
Another system that would be good, especially for bragging rights would be to take the smithing system and be able to unlock weapon parts to change on your class. For example, my varyag could transmogrify axe heads and handles to the axe which will be unlocked by playing the game or fulfill certain criteria. Example: engraved axe head after 10k kills etc.
