I can totally see where you're coming from, and I can assure you that everyone agrees that Midare feels better to use than Hagakure. However, my issue was never the removal of the skill in itself, but the lack of depth Sam's rotation will have in its absence. All the interesting decision making scenarios and multiple ways to build your rotation around it are gone. Now we get 3 sen and always do Midare, over and over again. I can't stress enough how mindlessly boring and repetitive that sounds compared to the many ways you can optimize samurai today. Give me some other way to utilize that Sen! Always doing the same thing is just sad.
Slightly more complex than your regular "come off CD/press it button" is a more elegant description. I can't see removing something 'cause people were unwilling to put in the effort to learn, thus having a "clunky" feeling, as anything other than reinforcement of below-average play and catering to lazyness. Haga is a solid CD and if feels really good to use too once your master it. Alas, its only sin was requiring a little more thought prior to pressing... so it had to die.
I see this being thrown out a lot, how people just wanna use Midare because it's cooler and Haga doesn't look impactful at all. To be honest, there are so many ways they could've have addressed this concern without dialing the job's rotation all the way back to level 60.
For example: have the new double Iaijutsu skill replace Hagakure. Instead of just being a copy-paste of the Iaijutsu used last, have it always be Midare. It would have the same CD as Haga and consume as many Sen as you had stored prior. Its potency would also vary depending on the amount of Sen spent. 1 Sen - weaker than Midare / 2 Sen - same pot as the Midare we have now / 3 Sen - 30% stronger than Midare, new cooler animation, can be used with Kaiten.
This was just a 3 minute example, but even with it, people would have an even better looking (and stronger) finisher, Samurai's rotation diversity would still exist, and you would have at your disposal a powerful new ability instead of mindlessly spamming even more of the same skill we have already been spamming for this entire expansion.
But nope, remove it. Copy paste the last Iaijutsu used, call it new.
I'm sorry but I can't agree with that in any way.
