2. Nightghost Guide - While the idea to boost duration of kishin seems good, it makes keeping this skill up quite a task in itself and makes it a chore to grind as a kanna. With what we currently know, Nightghost doesn't proc enough to meet the cooldown time (1 minute) in general. Instead of associating Nightghost with Kishin, I'd keep it separate, as its own thing, as it was Pre-Rise.
I have never seen a company being THIS out of touch with their playerbase
