Khorin likes his easy mode, just it. True, katana is more expensive than bastard and longsword, but is better than both. 3/4 speed for 6 reach makes the difference. Ideally, Katana would have 100 speed tops.
Exaggerating doesn't help your cause. It's 3 speed for 6 reach and 5 pierce(bastard vs. katana) or 4 speed for 11 length and 7 pierce. Speed is the katanas only advantage
When will you understand that the reason katana wielders are fast is because of their build more than the weapon.
For reference, here is my build:
