SAM improvements that needed in the next patch.

A simpler fix, or at least in my mind a more fitting one, would be to simply have Iaijutsu apply a status effect that Tsubame-gaeshi plays off, allowing you to effectively stagger the use of Tsubame-gaeshi to weave it more efficiently. To copy from Red Mages playbook, something like Kaeshi : Setsugekga Ready after doing a Midare, which lasts X seconds, allowing you to weave GCDs between Midarea and Kaeshi : Setsugekga as needed.

Going the whole "Samurai isn't a melee caster!" route, when that's literally been its gimmick since day one is... Odd, to say the least...
