I agree that there needed to be changes to the Nms but the method said here seems totally backwards to me. If this were 2 or more years ago then probably would be outstanding, but with the progressing of this game i feel like this is making it even HARDER to get the desired items.
I myself have seen Nidhogg, Aspid, and KB all unclaimed walking around several times on my server in the past few months.

Simple fact is people arnt going to farm KSs for these bc's and they wont be done after the first month of spamming what ks's everyone has, the only way this would be good is if the droprate for defending ring and ridill were increased.

My suggestion would be to switch it from KS to KC so its relevant to current play styles.
