Anyone like the Ninja changes? Let's look at what we saw so far.

[KageTokage]

It seems like the new skills are indeed just Meisui (Converts Suiton into ninki), the enhanced Katon/Hyoton, the new AoE combo, and Bunshin.

I don't feel like the NIN opener is going to be high ping friendly anymore as you'd need to double weave multiple times to get every single OGCD ability on cooldown within a single TA. The hardest part would be landing an enhanced ninjutsu and still having time to get off two TCJ boosted ones on top of that.

get off two TCJ boosted ones on top of that.

I gotta agree that it is indeed not going to be ping friendly, either high or low, really.
Not gonna be weird if later on the main DPS comes out of Ninjutsus instead of GCDs even.

I don't really understand where the 2 TCJ boost comes from tho?
TCJ is also a charged skill?

As they confirmed Kassatsu is one of them charged skills, and at least has 2 charges, I believe that with what we know so far the opener will roughly involve something like...
Huton > Hide > Suiton > Meisui + Mug (maybe) > TCJ Suiton > TA + Bunshin > Kassatsu Hyoton x2 > whatever other skills

In the opener alone firing away 7 Ninjutsus

As TCJ no longer consumes Ninki, most likely the Auto Attacks going off while rooted with it now actually gives you Ninki too. (Which would be sweet)

The hexagonal thingy that happens after Death Blossom is definitely an AoE melee combo that charges up Huton, hopefully also gives Ninki but I wouldn't bet on it...
