As a main of SAM from 4.1, I'm mixed. I'm mostly against the changes, in fact, heavily against the changes so far. I only like the change to Third Eye and Meikyo Shisui so far.
I'm also an advocate for the shinten/kyuten change for senei/guren. If I'd been in the forums before this fiasco, I'd have suggested those publicly the moment I saw WAR in ShB. The devs have the ability to make certain stats proc certain actions over normal actions, there's absolutely no reason they can't do that for SAM to alleviate the bloat.
I can believe button bloat more than the actual stated 'action bloat' because the removal of Kaiten only means we find other ways to fill that same gap, thus bringing us back to the very same 'busy work' they were trying to prevent.
A job being busy isn't a bad thing if it all flows neatly, and SAM was one of those that flowed really nicely. REALLY nicely. Without Kaiten, even filling the void with Shinten just feels... off. Kyuten spam feels a bit better than the shinten spam, but that's only because Tenka Goken has been neutered to the point where it's pointless. Tenka Goken needs to be up there with the other Iaijutsu casts for power and by hydaelyn, please make it a cone again!
Squishy dps don't want to eat 5 cleaves just to fart on the enemy.
Bring back Open Eyes. Make Third Eye into Merciful Eyes. Make Shinten into Seigan.
Make the meditation stacks matter. It can either have 1 button that changes based on the number of stacks or it can alter Shinten and Kyuten based on the number of stacks. We can keep both Shoha 1 and 2 if the way Meditation stacks work. For that matter, it kenki spenders could even add to the stacks.
Iaijutsu, Ogi Namikiri already build it and with more meditation stacks, we could have it where Senei and Guren build it, too.
A minimum of 5 meditation would allow all of these to exist without making everything a separate button for individual situations. Consolidate these redundant buttons into an evolving kit with Shinten and Kyuten being the base for these extra attacks that do roughly the same things.
It would both make the resources matter again, and it would also be more in line with the consistent damage they seem to be going for. Less spikes as it would just slowly ramp up more and more until you hit full meditation, and then rinse and repeat.
