my personal change would be: Bring back 3.5 MCH (minus rend mind, disable & promote as the job pool gives us that stuff) & throw 4.0 MCH out the airlock & into a black hole

Honestly miss Heavensward MCH, cast bar & all, I mean I'll use Stormbloods cause I can't bring myself to not use a gun in FF14 but that doesn't mean I'm gona like this "New" MCH
