About the whole unwinnable fights deal, I feel that they are almost never done correctly, and even if they try to do such fights in the best possible ways, they're still underwhelming. It's why most games nowadays don't do it anymore and I don't really remember any case right now - I've read FFXVI has an example but I haven't played it, but also Dragon Quest XI does and it's "probably" one of the few unwinnable fights where it's also an integral part of the story...which I can't tell because it's major spoilers.
Either way, I feel that they're really not fun to do, and don't tell you much at all about it, other than "woops, you can't win, screw you". I'm honestly happy most games have quit doing this because it doesn't do anything other than prolong a fight. If you wanted us to show we were unable to win just give us a cutscene instead, at least we'd lose with style!
This reminds me of a game that I absolutely hated for this annoying gimmick, which was the Trails of Cold Steel games: they constantly throw you unwinnable fights with enemies that are considered Godly beasts, and it did work...the first time you meet them that is. But after the quintillion unwinnable encounter, you just go "urgh, fine, let's lose quick". Heck those games even tell you "lower X hp to 50% to win the battle" and even if you're in NG+ with level 200 characters and final weapons, and being able to use your S-craft with quartz that double your attack on first turn, doing literally hundreds of thousands of damage, and yet you can't win against this boss anyway! So why even bother?!
TL;DR if you want to show us unwinnable fights, make it a cutscene instead. At least it's an enjoyable defeat rather than a meaningless win.
