i like some of points but i dont agree with the savages having so heavy punishment, damage down and vulnerability are already a thing in some fights and having those maybe last for the entirety of the fight making so that everyone plays 100% correctly and avoid every possible mechanics can make jobs where the strong points are the versatily on save a run with a clutch move even more rare, thats one of the reasons i love to prog as PLD and maybe switch to other tanks to speedkills.

But what got me to the tank role for exemple was the mechanics for job that allowed me to control the fight and interesting mechanics possibilities, i remember how cool it was for me ditching the boss to the OT and running getting the adds on T7(Melusine) or positioning the adds correctly on Helicarnassus. Things that only a tank could do, i wished that every job could fill a role in the fight, more usage of the role traits, silence, esuna, stunning bosses or adds, dealing with Preys, now that almost every class has defensive cds.

Not necessarily more punishing but more creative. moving away from every "Role is a DPS" Meta.
