Endgame gearing is one of the worst aspects of FFXIV in my opinion. Substats are boring and almost always just come down to stacking as much crit as possible. There's nothing special or interesting about any piece of gear as it's just slightly higher numbers than what you already have. I understand it's easier to balance this way, and it's a lot harder to have job specific augmentations on gear with the job system, but having everything so homogenous is just so boring.
