You can check out Galvuu's other thread. It sheds light on how the 4.0 skills and their proposed changes to our rotation is ultimately futile. It seems that SE did the "This piece gear is different because the colors are different" treatment on us. The PPS of the 3.0 rotation is almost the same as our 4.0 rotation. The only significantly good thing Stormblood gave us is the incredibly powerful AOE potential thanks to T4P and UH letting us Flare>Foul>Flare every AF window.

Feels bad man.
