As I remember FW had some special classes like marshal now my idea is to improve and adapt it to current PW.
What I want is special classes and armors for each class and a whitelist system for it. For example every clan got an Archmaester; There must be a special whitelisted training for this class, heals better, faster or maybe able to wear better armor than common doctors. Same for a specialized kg class which got better fighting stats and able to wear kg armor(which will need 18str for example while sgt or maa training got only 15str). Also a special armor&horse for maa.
Trick is to make them whitelisted so only limited people will be able to train them. This will add some colour to clan rankings and make actually being good in your class means something.
I’m open to improvements of this wonderful idea.
