In one of the developer comments last year it was mentioned that further tiers of dragonmarks would be enhancements, not feats. (as in take the least dragonmark of X as feat and then take lesser and greater as enhancements)
Current situation on Lamania:
- Continued Dragonmarks are still feats.
- Dragonmark enhancement lines(more uses) that exist on live servers are gone.
Thus instead of improvement it is a step down for dragonmarks. (That have never been very special to begin with, more a "fun thing")
I hope that this is an oversight that will be fixed before the things go live.
