People brainstorm rotations, calculate formulae, code/re purpose programs and addons, debate, and collaborate to find the best and/or most efficient way to play their classes.

There's a reason that there is a "meta". If you're going to be hard-headed and respond with "but this is how I play" and waste other people's time, just uninstall FFXIV.

I'm looking at you undergeared, DPS stanced tanks who think they can hold aggro using taunt, Ice Mages, and 1000 DPS/second BRDs.

This isn't "Fight Your way."
This is "Fight this way or GitGud."

No seriously:
