If they did spend time separating them... if anything that would just hurt job balance. If they have to spend time making separate class mechanics and spells for every job, that's less time they can spend balancing the version of the jobs that needs balancing.

I really don't see what this request accomplishes beyond wasting SE's time.
Well if all that was the case, why make a separate class system/bar for PVP when they probly just coulda kept everything in the classes the way it is, and just tweaked hp and dps numbers? since the classes are so balanced already by your example they basically just wasted their time on changing (and even now constantly balancing) the pvp system.

balance SHOULD matter in casual content, but BALANCE should NOT take priority over FUN and unique mechanics and gameplay, CASUAL content should be built to appease CASUAL players, just as COMPETITIVE content should be built to appease COMPETITIVE players.

as ive stated enough times before, SE has trapped themselves in a box of balance, so much to the point where classes and their abilities and numbers are basically built around being viable for savage gameplay, and anything that so much as steps toe outside of this box is apparently so game breaking its just disregarded as NoT PoSsIbLe, even though the extreme and savage gameplay only accounts for 10% max percent of all the game has to offer, meanwhile the players who dont even do competitive content like that are just left with the "eh... there's nothing wrong with your class " people.

Why do you think FF14 has had and still has its In need of HEALER duty finder problem? Why do you think so many ppl are upset, and have even dropped the healer role all together? Why do you think so many ppl are upset with the way they did Blue-mage (arguably one of the most interesting and wanted classes, a borderline staple to the entire franchise) -- ruined and thrown out all to appease Competitive gameplay , which again, is not really even 10% of the game.

No, it would not hurt job balance, nor would it be a waste of time if they were to separate the 2 areas. In fact it would open up the dorr to so much possibility and freedom in class, level and dungen design SE could take advantage of -- it would give them a way out from the box they've built (hek, they could possibly even still let the competitive sets be able to be played in casual areas, just for thoes who like the old ways), but regardless there needs to be something done about the rift between the 2 player bases, but as it is now the vibe im sensing from the devs are Competitive endgame is the way to go, and Casuals be damed -- or at the very least thats the vibe im getting from the Elites.
