Making jobs spam the same move more than once feels boring

My point isn't that number increases aren't you getting stronger, it's that number increases alone aren't enough to make a class genuinely feel like it's getting better.

But even in Warrior's case, it doesn't just have number increases. That's just the specific effect of Nascent Chaos. And there is also something to be said about not completely changing everything, as you've said. So you can use Fell Cleave more at 70 and you can upgrade Fell Cleave at 80. That's a nice, steady progression, along with other changes to the job, most notably in Shadowbringers being the tank changes where you don't have to sacrifice defense for offense in terms of enmity management.
