Nooo! Leave then!
Don't make it 110% super highly historically accurate! I like some random stuff, they enrich the gameplay! I think you could add more of then!
Rebalance is good, but add even MORE items will be better (in my opinion, sure)! Dont remove any!
Is possible to add more comissioned items or make they more costly? After you buy some of then, and it isn't THAT hard, you don't have to buy new itens anymore... Even lordly high tier armors, who costs more then black armor, dont have 70 def...
