Using my own words, and using them poorly at that, isn't doing you any favors. My own opinion on the current state of Machinist is pretty neutral. It's just a less punishing Stormblood.
This river blurb is interesting because it is full of objectively wrong information.
Not a single skill wasted: Warden's Paen, This is basically the equivalent of Mach's Flamethrower in breadth of use. There are very specific cases where it has use, but then so there is for Flamethrower.
Everything aligns: Man, do the other bards have words for you.
Mindlessly mashing skills: Literally Heavy(Burst) Shot. Hope you proc.
Rotation Roadmap: You can literally map out every single GCD and OGCD usage on Machinist. You cannot on Bard, primarily because its based on procs. You can, however, plan most of the important ones - Namely your Barrage Refulgent and your dot refresh Iron Jaws, and your song windows.
