Each expansion since Stormblood has ramped up the difficulty. Shadowbringers wasn't too punishing but bosses were damage sponges. Endwalker bosses had more moderate hit points but were harsh towards even small failures.

For the most part Dawntrail takes a happy medium but there are like three or four bosses who are overtuned. Overly punishing mechanics that fill the entire screen and often aren't clear about what you're supposed to do. You can typically survive a shot or two from them but they like on so many mechanics at once that recovering can get overwhelming.

I'm not looking forward to grinding back through them on other characters.
