Im now playing this game for a very long time... since 2014 february and i rarely have something to say.
I started as a Monk, played it in t9 and ohter stuff until ninja release, then i played Ninja in savage raids and in every other content that was available at that moment.
THEN! Stormblood and Samurai got released and i knew for myself im going to play it and i will stay on it to the bitter end, raidgroups take me as sam or leave me be.
Thats what i said all those years, ARR, Heavensward, Stormblood, Shadowbringers, Endwalker and all of my raidgroups that i had, had no problem with it. The fact that i enjoyed my class for that long time motivated me and made me having fun to play/learn Samurai and beeing atleast good in my and others opinion.
Samurai felt even more great under my fingers in shadowbringers and endwalker made me felt like i had a time and space shattering killing maschine with up and downs, pros and cons. Sometimes it was frustrating because i saw my midares or ogis not crit once in a fight.. beeing a good dps was never only skill based and i knew that, if you add critchance to a game your character becomes a gambling rollercoaster, but i was fine with that completly. The excitement of pressing kaiten and seeing how heavy and satisfying those skills could hit was amazing as hell, it was the best for me, my entire raidgroup cheered for me to make this midares and Ogi go through the roof for them and now?... look what we have here... a flat and bland, grey, colorless, boring treadmill... the excitment is gone, the feeling of having a actual force under your fingers got deleted entirely. I miss kaiten in my rotation, i still press it out of muscle memory and i get confused because nothing happend, then i remember 'ah.. im kaitenless, i forgot' and then i see that bland, flat number of my midare and ogi and i think.. wow.. that feels horrible, theres no impact anymore.
Playing Samurai now feels like tasting one of gordon ramsays horrible kitchen nightmare dishes that taste awfull and empty, its a straigth line with no up and downs, well... there are still downs because the upper ceiling of that class got flattend to the ground.
My Suggestion would be to bring back Kaiten but change it, if you want us to autocrit more to make us more consistend... give it to kaiten, i guess a bit potency loss has to be there to balance some stuff out, its necessary but not until the players have to question themself ''why does it feels like nothing?''
I appreciate the idea of making us more consistent with our rotation and big htis but this feels completly wrong.. it killed my fun playing the game and Samurai in an instant and i honestly was not able to enjoy the new patch that way either... worst patch experience that i felt in FFXIV actually.. and the last time i felt like this was in WoW Wrath of the lichking at the end of the addon where Blizzard destroyed combat rogue completely for me.

Please Yoshida and the Team adjust it carefully.
