For Samurai, I wouldn't be surprised if they consolidate a lot of the moves. There are two 3 skill combos you use to generate sen and get the buff (dmg and attack speed). There is a 2 skill combo that adds the slash debuff. I wouldnt be surprised if they use the PVP samurai skill system and just have a single skill that changes depending on how many times you press it. That lets you nuke 5 skills/buttons. There are also 2 base AOE attack that combo with a slash opener (if you use the slash opener, it buffs the AOE and also generates sen, letting you use the 2 sen AOE cone attack). I could see them simplifying that as well.
The level 70 samurai attack is clumsy to use and limited value outside of AOEing down packs of shit. However, it is on a long CD and because it is tab target, it can be hard to aim the attack properly. They should redo it completely or make it easier to use. Why not use the attack from the Stormblood cinematic? Target a spot on the ground and your character rushes through everything, doing damage.
The level 60 skill (the thing that lets you generate kenki?) needs a rework. It's only usable in combat, which makes it kind of garbage "hey guys, I'm just going to sit here for 60 seconds to fill my meter and not do DPS". It they made it work outside of combat, that would make the skill a nice pre-battle prep tool. Especially in level sync content when generating kenki is a pain in the ass.
The open eyes thing also needs a rework. On paper it seems cool, but literally the only thing I use it for is I pop it before an enemy uses an AOE so I can get the self-heal proc. It would be cooler if they buffed it a bit more/let it contribute to the party somehow.
In terms of things to add, I'd love to see more mobility. It's one of the things I love about the class, so I'd like to see more options.
