I'm curious as to if this is your main and if you've progged Savage etc?
If your experience in FFXIV is MSQ, leveling dungeons, experto and 24 man, then you're 100% correct. You can chuck most of your hotkeys in the bin, mindlessly smash 1 button, play wildly incorrectly and you'll still likely make it through just fine and the game makes zero attempts to try and push you to improve (And any players that try that are risking a ban these days, gg).
Step up to Savage prog and beyond and BLM isn't so simple all of a sudden. A big part of it's popularity is that it's got a lot of room to optimise compared to most other jobs and during prog, getting that optimisation right is generally pretty important or enrages will likely be a bit of a hurdle.
