About a week ago I was only joking when I said that if a job plays as well as SAM did prior to EW, the next step after that is to tear it down. It would appear that all jobs can essentially be looked at like a house of cards, or a game of Jenga based on these comments from Yoshi.
It is perfectly understandable if Yoshi and co. feel a certain pressure every expansion to add something new and exhilarating to all the jobs. It is also understandable if they get stumped trying to not only come up with, but also implement new ideas into an existing system while simultaneously working on improving elements currently in play. They're not going to hit the mark on all the jobs. I think adaptation is a favorable skill to have in order to continue to enjoy FFXIV as changes come.
However, I feel it is a rather simple concept to not fix what isn't broken, and building on top of what is already working can lead to it collapsing under its own weight if you are not careful. When you make unfavorable decisions and changes, and the feedback you provide is even more questionable, it feels the exact opposite of being transparent with your playerbase. I believe a lot of animosity towards the dev team is created like this.
An issue with something like the removal of Kaiten is it is mentioned to the playerbase far too late for them to do anything about it. It is force feed, and we have to just eat it whether we like it or not. It makes the pleas from the playerbase to reconsider the change null and void. There is no such discussion from dev to playerbase concerning impactful changes. I can understand additions such as a new skill or trait coming in a future expansion needs to be kept hush-hush, but I am talking about changes to existing skills and systems.
If there is anything I can suggest for the dev team it would be to stop force feeding the playerbase. It's a big reason why the feedback given is made to feel like it doesn't even go in one ear to go out the other.
