My take on Meisui is to consume the Suiton effect when TCJ doesn't line up with the trick cooldown, what way you'd still come out on top with ninki (assuming you don't overcap it) to push towards a bunshin or bhava. I'm not sure about TCJ under trick, it doesn't feel right in my head and I'm not going to say I'm great at the whole theory craft but I feel like bunshin will be the go to for trick window, assuming the clone's damage is respectable and I would assume it is.

Expanding on our AoE with Death Blossom > Hakke Mujinsatsu is going to be really nice. We are losing 100 potency on Bhava, but with basically no CD? it's a buff out right imo. The two new ninjitsu from Kassatsu (on top of kassatsu having 2 charges and half the CD we have now) I welcome with open arms. Might not be promised crits but there is still a boost in damage and new toys, can't really complain. I wish it told us how much the boost was though.

We'll see what the (official) numbers are once we get our hands on it first hand as we don't know what may or may not change, or errors in the tool tips from the media tour. The math boys and girls that theory craft and test their hearts out will be all over this and I'm sure they already are looking at these even if they change. Till then, trying to contain my excitement for the xpac is... getting really difficult lol.
