The class system that Bannerlord is using just isn't fun. It will become Meta with certain class choices just being bluntly worse than others. It sounds simple but each class should have benefits and weaknesses and they should remake this entire gold system they've introduced. Some units that are mediocre are too expensive and others that are too strong are too cheap, Archers especially are broken.
What concerns me the most is the implications for this system in servers that try modding, like RP servers. It could kill a lot of the community that still play Warband to this day, I'm sure a PK-esque mod will still be developed but small scale servers that try to run RPs probably won't work anymore without heavy modding. Which we no nothing about because TW won't give us any information on what they are developing.
