Why is everyone anxious about a PLD Rework?

[Absurdity]

from what i've heard DSR is the hardest encounter ever even though people are playing "brainded jobs that are impossible to screw up", so...

Ultimate is designed to be difficult even if your job is braindead, that's what the mechanics exist for.
All DSR proves is that they can make mechanics difficult enough to create an engaging encounter even with lackluster job design.

But this is exactly the problem. Sure DSR has hard mechanics, the other ultimates do too, even some savage fights have hard mechanics, but you know what doesn't? The other 95% of the game where the mechanics can't make up for how lacking the actual gameplay is and in which these ultra simplistic jobs just make everything so incredibly boring that you question why you subject yourself to 95% crap for those 5% that are actually good.

The game previously managed to strike a decent balance between the difficulty of just playing your job, or as I'd like to call it how engaging your job could be to play, and the difficulty of an encounter's mechanics. Now everything has to be carried by the mechanics and where those are lacking the entire fight is lacking.
