I think I'm starting to understand why with the responses I've read throughout the thread. The irritability comes from the battle team attempting to fix PLD into the 2m Burst Window compared to the other tanks that do, and it comes with the belief that they're going to remove crucial parts of what make Paladin Paladin. Same with the anxiety; I can relate this with the removal of Kaiten from Samurai. Core Gameplay mechanics being removed for less complexity in a job's rotation.

It makes sense. If I had to name one thing I think they'd attempt to remove, it's probably Fight or Flight being removed and pushed into potency for PLD's Goring Blade and Royal Authority. Just staring at PLD's rotation tells me that their GCD Rotation for FoF is too long(11 GCDs) compared to Requiescat(8 GCDs) to the point where they are forced to Atonement drift if FoF doesn't line up perfectly. That deviation isn't present in the other tank's kits due to the fact that no other tank has two burst phases like PLD does - and that's what creates that complexity and deviation in PLD's damage. Breaking it down, every buff optimally is up by the 4th GCD. PLD has to go out of its way to waste 18s worth of FoF in order to line up their damage for the buff window before the pull starts. Other tanks don't have to do that. When PLD comes out of a phase transition, they go straight into their FoF window since you have slightly more damage there than Requiescat; or they go into Requiescat if they can't fit all 11 GCDs into the buff window(spoiler: THEY CAN'T). However, the damage difference between the rotations is very slight, by about 15 potency.

FoF Rotation: 5,525 potency total(after FoF calculated into rotation)
Requiescat Rotation: 5,510 potency total

Removing FoF would get rid of the complexity that PLD has currently, though the question is is this complexity needed or is it needless? It's something to think about, since I can't make heads or tails of whether it's needed or not due to PLD's current nature. The main thing holding back PLD is the fact it has a 11 GCD rotation in FoF while Req has 8. When you're doing the general rotation, there is bound to be some desync between that and your FoF coming up due to Atonements in the "filler" phase after Requiescat as I mentioned before; the question I'll leave at the end here is how would PLD feel for you if FoF didn't exist?

If it didn't exist for me, I'd still be following the 2 Atonements during filler to keep things going without having an extra layer of complexity to worry about during the filler phase. Whether I should give up an Atonement or not. Whether I should hold a GCD for FoF to line up perfectly. It can be determined as skill expression, but it feels like it's a constraint at times during fights that don't have 100% uptime.
