If you use Wazabane with a sword in your main hand that is not a katana, and a katana in your off hand, you will always use the katana regardless of ambidexterity. This is bad if you want to, say, use a 4m wazabane with an excel saber.

Not a bug, they will always prioritize the katana. I wouldn't expect this to change either.
