I like most of the SAM changes, but there's a couple things of note:
  1. The devs are continuing their long-standing tradition of bloating ability bars with AoE and single target exclusive versions of low-use skills (Shoha vs Shoha 2). I don't like needless bloat especially when you add single target exclusive things of aoe/ST hybrid abilities and so forth.
  2. They're bloating the AoE rotation with another GCD, because they wanted to add a third bar. This wouldn't be a problem if it weren't for abilities like Shoha vs Shoha 2 and every identical analogue.
  3. Tsubame-Gaeshi will still cancel if you accidentally use another GCD, at least the charge system means it won't drift if you mess up. This is also problematic if you need to shoha between a Midare and Tsubame because it tends to clip due to ping and such.
  4. The most technical class in the game by raw keyboard button presses and systems to manage just got more technical due to more buttons to press.

That's really it. The class will have about 35 or 36 actual hotbar buttons, a lot of which will be exclusively AoE filler bloat, and the class has long since passed the point of being pretty bloated. I consider most hotbars bloated at about 30, which lines up with complaints about button bloat back in Heavensward. The class didn't need much aside from fixing the bloat and dropping the skill floor on Tsubame-Gaeshi, while it wasn't quite dropped, it was at least made more tolerant to drift, so it's really just a lot of bloat.
