Something that would insanely help make the SAM fluid would be (IGNORING THE NUMBERS THAT CAN BE ADJUSTED):

- Remove the casttime
- Make Soten auto trigger the current Yuki/Gekko/Kasha Combo but not more than once per switch
- Make Mineuchi do more damage when current health is low not max wtf
- Increase Chiten uptime from 5 to 8 and lower the bonus damage
- Remove the onehit LB and replace it with something that has way lower CD

Right now SAM is just fundamentally broken, not unplayable but just unenjoyable for absolute everyone.
It's a lot of work on the other hand look they can't even deal with NIN and all you have to do there is:

- Set Seiton to max 2 usages
- Remove Meisui (Optional)
- Make Stealth not break the first 2 seconds after usage (Optional)

and all DRG needs is:

- Increased Movement speed
