Don't get me wrong. I agree that Dawntrail is a giant shitpile right now and that things DEFINITELY need to change going forward. But going scorched earth and wanting so many heads to roll is not really feasible and won't get any criticisms and concerns listened to. My stance is Hiroi and the current MSQ team shouldn't be fired, but instead brought back down to the side-quest/side-story writer status since that seems to be what their specialty is. Firing them all just really isn't viable depending on what is going on behind the scenes.
All you have to do is look at some of the massive threads that have been on for several months / years about various issues and complaints players have had, only to see absolutely none of it be heard. I may have hated Endwalker Main MSQ/Endwalker Post/Dawntrail Main MSQ, but throwing whole teams of people into the garbage with potentially no back up ready is just...not viable. Sure you COULD drag Ishikawa, Oda, and the old team back, and I am sure they would do it. But eventually they WILL just not want to do it anymore, and if the old devs/writers are not going to help the new devs/writers get some footing with that they're putting out then it's only going to keep going downhill.
Don't get me wrong either: I'm definitely not defending the work they have put out given how I've complained about DT in several other threads. But given how Square [Not the FF14 team, Square themselves] have pretty much pissed away so much money the past several years with a "quantity over quality" live-service game mindset along with just throwing so many projects into the dumpster: they probably either give FF14 pennies to work with, or give them none at all. It's a genuine possibility that currently there is no backup plan they can fall back on and it's something you have to consider when looking at the bigger picture. Yoshi-P and the rest of the 14 team might just genuinely be up a creek without a paddle and there is a hole in the boat and Square themselves is just shrugging at them and going "You'll figure it out, or else" and leaving them to fend for themselves.
Yoshi-P has stated he wants younger generations to handle the future of Final Fantasy, like with FF17 for example. But right now specifically Yoshi-P and the creative studio III team just might not be able produce the results they want, be it because they have stretched themselves too thin working on too many projects [like they announced they are doing currently], or because Square needs to throw away more money on shit that'll flop or be shut down a year or two later, so they won't spare FF14 pennies right now and are just banking on the fact the hardcore fans WILL continue to pay and play no matter what.
