Tbh while I'm empathic on the issue I feel like this is what can be considered the skill ceiling.

You don't have to give yourself carpel tunnel to clear content, you just aren't going to get a 99%

It really does come down to player choice on how much they want to commit to the ability of the class.
You used to be able to be very anal and micro manage the shit out of fairy on SCH, nobody did it though.
You can even micromanage Kardia on SGE, nobody does though.

I remember back when trick attack was some 10 seconds and the question was what abilities/skills are you going to hit, not what abilities are you going to miss.
Not so much since Endwalkers dropped but AST at its core without cards was just a knock off whm and you could clear content just fine being a knock off whm.
