Exactly my qupis with the jobs in general, even healer and tanks suffer from this "lobotomy" theirs 101 ways to fix it but MCH...MCH isnt a simple fix or shift in DPS it needs a overhaul which sadly wont happen since the general population thinks it already had one but in rwality it lost more than it gained.
Ranged roles have suffered to this aswell "Physical ranged DPS attack foes from a distance. They excel at inflicting sustained damage, and also provide support for companions."
BRD and DNC are all hunky-dory with buffs and team support but this Information taken directly from FF14 Official site, and MCH has nothing besides "Role action" buff every 120 that literal every ranged has. So its wrong MCH should 100% support! Ranged jobs with DPS capabilities as BLM or MNK but not really isnt what ranged is all about unless they can alter the definition of a Physical ranged DPS
