I've been playing Samurai since 4.0, (played NIN in HW) and I've really loved how it plays. The only thing I can complain about it right now is that it doesn't do enough dps to compete w/ the other melee's utility. Other than that it's fun and satisfying to play!
What I like:
-AOE combo finishers extending buffs, (no tp cost for gcds now) which is really nice QOL.
-Cast reduction for iaijutsu, might be able to weave something after casting.
-12% shifu & jinpu is nice.
-Senei: single target version of guren, animation's really cool too.
-Shoha's animation, it's sick.
-Double iaijutsu's kinda cool, wish it was a different animation for the second one.
What I don't like:
-Hagakure being replaced by a CD that gives you a flat 50 kenki at no cost. While this is a buff to our actual dps, hagakure was what made SAM's rotation interesting. It was perfect for managing sen. Coming back to the boss after downtime/starting a dungeon pull with 2 to 3 sen is really clunky.
-Seigan still exists. It's such a minor dps gain, and having to be damaged to use it is silly imo. I would rather it be removed.
-How shoha functions. The ability is super underwhelming especially for how cool the animation is. The amount of times you can get a full meditate off is pretty rare, and I don't like the idea of a skill that gets better if there's more downtime. There's a lot of suggestions on how to fix this skill in this thread: http://forum.square-enix.com/ffxiv/t...rai-Lv80-Skill.
One thing I want to suggest is having meditate being reworked. Instead of it being a channeled ability to use during downtime, it could just be a buff that works similarly. It could give kenki, and stacks that last until you use shoha, or just allow you to use it a flat potency. The amount of kenki you get per tick might need to be adjusted, but the ability would be more useful overall. Also the red glow could cover the katana after meditate is over, and would go away as you use shoha. That would be super satisfying as a level 80 skill.
