The four set looks amazing! The two set is ok too. I think the two set will help sub a lot, and C and A a little.
The four set means you can't stack AR and blades, but... who cares? I mean, this tier is crapping on combat as it is, right? I think we have to play something else mostly?
Btw, get a load of that blade flurry. When does combat benefit from running fan -> tempest? Because it looks like it will have a confusing priority that doesn't matter if you mess it up because the aoe damage will be bad no matter what you do!
