Koga Chainmail is absolutely terrible armor whose only proper place is on a Storage Slip.
I don't give a crap if people want to mess around with obviously bad gear, knowing that it is bad, because they're solo and like2style. But I won't be so lenient on you if you seriously come in here and try to tell people that Koga Chainmail outperforms Loki's Kaftan, on anything, ever.
Koga Chainmail is worthless. If you think it's better than even an NQ Haubergeon, you're wrong.
