As a tank, I shouldn't be needing to rely on a Shirk macro or the co-tank to wait to turn on tank stance so that they can be second on enmity list in case I die for some reason that was well beyond my control, and waiting the co-tank hitting provoke AFTER I DIE FOLLOWED BY BY AT LEAST 1 DPS DROPPING LIKE A FLY(the death usually a slow reacting healer of some kind, though mostly server ticks from what I can tell), and if the devs needs to put in a tutorial on how to use Provoke, Shirk, and Tank stances, followed by a tutorial about enmity combos when you join a party(that people are going to ignore by the way because of course they can and they also don't read tooltips)even though enmity combos are no longer in the game(probably forever until the servers shut down)and people still complain, then devs should just focus on making a better tutorial system that is based on the class/job you picked to replace Mentor system(ever since the progression skip boosts were implemented and can easily be abused so long as people meet the requirements to become a battle mentor), the Novice Network, AND the Hall of the Novice.
And how to fix enmity combo being DPS loss is just make it generate the same amount of resources as your main DPS combo, buff the main DPS combo to have effects that benefit you from main tanking(using DRK as an example; Syphon Strike restores HP and MP with Souleater Restoring HP and generating blood gauge, with Spinning Slash restoring MP and generating enmity and Power Slash generating both enmity and blood gauge).
It's not that hard to come up with a solution once the damage is already done, but it's also as easy ignoring potential fixes to a system that is mostly based on player issues, skill/ability/trait issues, or both(see BLM and SAM) and it's just as easy to strip enmity management to just a toggle for ALL TANKS just because people don't like playing tanks. So far only GNB and PLD feel like they were designed with the enmity toggle in mind this expansion, whereas WAR and DRK were not...
And if you think enmity combos aren't needed for at least 1 tank, let alone 2, then I think melee positionals are no longer need, are an outdated system that no longer fits with the games(which if people actually agree on melee positionals need to go then FFXIV is going to lose a lot of it's playerbase and the people argued against enmity combos are going to reluctantly be all for bringing back enmity combos and melee positionals to comeback and I actually do want melee positionals to stay but who knows at this point), along with the current consumable items system(though this argument is more legitimate because consumable items share a recast for some unknown reason), and Limit Break needs to go because of hard it is to use in group content(WHY IS THIS STILL LOCKED TO BEING IN A PARTY AND SHARED BY THE REST OF THE PARTY?! THIS IS EVEN MORE ILLOGICAL THEN PEOPLE ARGUING AGAINST ENMITY COMBOS!!!)
