Indeed, so if you make one dagger SQI, you automatically need to make two dagger SQIs. And then if we make dagger SQIs we need to attend to the other forgotten weapon types like 1-H Sword, 2-H Sword. And then all of these even before poor Ninja gets it's own SQI?
It just seems unnecessary, there's really nothing wrong with daggers at all as it is. TF is just more viable for the WoE setting. Even in NSQI Katars are more popular.
