CD Rotation For A1S

[Freyyy]

As DRK I'm using this CD rotation :

First buster, during Hydrothermal Missile's cast I use Shadowskin + Conva. Then DA + Dark Mind + Shadow Wall in the following GCDs to have them up for both Royal Fount and Hypercompressed Plasma.
Second buster, pretty much the same without Shadow Wall.
Third buster, Living Dead.
Fourth buster, same as first buster, but the boss generally dies before.

My co-tank is a PLD and he uses HG on the second one. That's why I decided to use LD on the 3rd, this way healers can focus on me for the second as I'll take more damage because I don't have Shadow Wall, and for the 3rd one, they can focus him because he doesn't use Sentinel and keep it for the 4rth if it happens.
I tank out of Grit most of the time, only turn it on between Photon Phaser and Hydrothermal Missile and turn it back off after Plasma when I'm back at full HP. For the 3rd Plasma I don't activate it at all because I use Living Dead. I use Foresight, Dark Dance and Reprisal to compensate the lack of tank stance. I also use Shadowskin and Convalescence in that fashion for the phase where I'll use Living Dead. This fight is really easy in terms of CD management because busters are really far away from each other. WARs can pretty much use Vengeance + IB for every Plasma and use ToB + Conva and Raw Intuition when they're on Deliverance to compensate for the lack of Defiance. This fight is perfect for WAR.

It also happened that I feel so confident about healing that I don't even activate Grit for the 1st Plasma (and 4th if it comes). Only if I have Reprisal + all my CDs + healers not struggling too much. I ask them before doing that of course.

It may not be perfect but that's what we're confident with.

Edit : I run with 3 slaying accessories and 2 fending. I have 16.4k HP on party with morel salad HQ.
