You'd have to have the eye and have used it to know the drawback, right? Fair enough, the questionmark was there for a reason. Thanks for the clarification.

So, Blaze release is essentially a pseudo-release, probably because it's a lot easier to say than Amaterasu Control (or whatever the actual name) every time.
