I honestly don't understand where all that katana hate comes from. I don't see many katanas on EU1, since majority of 2h goes for the longest possible greatsword. Although I don't understand why the stab is so low. For example compared to heavy bastard sword, the swing damage is just 1 point higher, but stab 8 points lower. It wouldn't matter otherwise but it gets your weapon stunned way too often. And since katana is almost 2x more expensive than HB, those stats seem a bit weird.
