Really don't like Hagakure I feel like it has almost zero use unless you need to drop your sen for whatever reason and using it instead of Midare feels like giving up a core part of the class. But everything I have read claims it is a dps increase so I am trying to adapt. That being said I have only been using it when I have 3 sen. However doing this it replaces 2/3 of my Midares, is this what I should be doing? Or should I be using it on cooldown even if I only have one or two Sen?
