Fine, more poll options. Happy now?!
Anyway, obviously if the items were removed then cRPG's dedicated item team would work tirelessly to replace the removed items with new more historically accurate ones.
As for pros and cons:
Pros: we would see a more historically accurate mod. Armour and weapons would be as period-accurate as possible, and possibly this would increase the general aesthetic of cRPG, since the items would mesh better.
Cons: we would lose some items that might be very popular. Possibly you could argue that this would limit choice, and that 15th century items (for example) add to the unique feel of cRPG.
