PVP kits are simplified versions of PVE so it makes sense to strip away a few layers and mechs

As for the topic, it would be weirdly specific on which jobs get it since most rotations arent a simple 1-2-3 no job has that much of a mundane rotation (besides MCH), DRG need to branch out for disembowel and chaos, Ninja with there Huton extention in armor break, MNK is all over the place, SAM would be entirely pointless as its too fluid. This would only benefit GNB rotations, MCH rotation, mayybe DNC which is only 1 button, RDM physical finisher and most of the aoes.
