Combat system is beyond saving.

[Aravell]

If the rotations were difficult then the fights themselves can't be complex, reducing the fun aspect of them.

The combat system is deceptively complex and demands perfect execution and optimization in order to compensate for mistakes that happen elsewhere, with harder fights having less room for that.

Damage optimization while doing raid mechanics and coordinating with party is where the challenge is, not the individual aspect of your character.

People always claim that complex jobs can't exist with complex fights, but why does it have to be one or the other? Why can't there be a good balance between the 2?

If you take complex fights to the logical conclusion, you get what we have now. Fights with debuff overload that requires you to parse all that information within 5 seconds or less and execute it or your entire team blows up. Is that fun? Depends on the person, but I find that kind of design highly frustrating, it's also a bigger wall for less experienced players than harder jobs were.

Look at Golbez EX, people have been likening him to a savage fight. Is it because he does a ton of damage? No. Is it because his mechanics are fast? No. Is it because you have to do his mechanics in very specific ways or your entire team blows up? Yes, that's exactly it.

Balancing fight and job complexity would stop this trickle down effect that's gating more casual players out of farming extremes due to pure frustration. You could carry a bad player back in HW/SB, you cannot carry a bad player in EW design because that player not understanding the mechanic will blow all of your up with no hope of recovery.

Edit: Come to think of it, even stack markers have been Endwalkerised, you can see it clearly in Another Mount Rokkon. First boss has a regular stack marker, do set damage and split among players if more than one. Second and third boss have a different stack marker, if one person, it does a million damage, if 2 people, it does set damage. Another case of "do mechanic this way or die", can't even choose to hypermitigate stack markers anymore.
