MCH is also the only class penalized for having too much skill speed. Which players will have felt this patch because of the Tome Weapon/Chest having it as their main substats. The melee dps and BRD don't really want it, but they're not hurt by it in the same way. RDM and SMN have some minor breakpoints with it, but like BLM they only really want more of it for some QoL based on ping.

The only real option to deal with it is to delay Barrel Stabilizer if you want to retain fluidity, because Cooldown takes too much heat off your bar and Flamethrower takes too long. It's something you have to test when you equip new gear, just to be safe.
