I didn't notice that, that's neat. Now it just needs to not break on executing another GCD and it will basically be fixed between charges and such.
Honestly, and I'm not a SAM main so take this with a grain of salt, Hyosetsu is such a bad ability that I'm probably not going to put it on my bars. Same with Shoha 2. I might even consider pulling Guren off but at least it has a use in level 70 dungeons. Samurai is such a heavily skill bloated class that the devs choosing to make the class actively worse will be met with me actively protesting the abilities that bloat out the single target rotation.
I really don't care about 10 extra potency and a 1-2 1-3 2-3 1-3 aoe combo rotation isn't going to cause me to bloat my bars more. I'll take the fractional loss to AoE DPS rotations.
I am seriously sick and tired of the devs taking perfectly fine ST/AoE skills like Guren, or Foul, and adding an extra button to split it from a ST-exclusive or AoE/ST hybrid button into a dedicated ST and dedicated AoE button. Nothing exemplifies the problem of skill bloat like a button you'd only press once every 20+ seconds while not making a choice but both being mutually exclusive.
Or, to put it another way, the devs when looking at RDM went: "Let's make RDM's ST combo also do aoe damage." They didn't contribute to bloat on the class, and it functions just fine in both ST and AoE. Samurai is not made better for having more button bloat, especially when in the overwhelming majority of situations, including raid situations, that bloat is a meaningless waste of hotbar space.
HW had a major amount of backlash due to having classes at or above 30 buttons per class. That's including all class skills, job skills, and cross-role skills which were limited to 5, as well as sprint + LB. I don't know why, but the devs seem hell bent on repeating this mistake, so showing them that it's a mistake by not even using it except in something like an ultimate fight that actually demands it would go a long way towards fixing the problem of unnecessary skill bloat.
