Why doesn't pve have pvp combo structure?

[Rymi64]

As I said, there are at most two jobs that use a straight 3 button combo.

No matter what the rotations tend to be self centered. Most of the conditions that determine what button is to be pressed are internal to the player character. Combat should be more reactive to the opponent. Rotations shouldn't really be a thing in RPGs. It should be based on the needs of combat. It's all regressed in recent years and today's designers are kind of short sighted.

The jobs that could get away with having them consolidated into one button are DRK, GNB, and MCH (one could argue PLD WAR and NIN could also get away with it).

Rotations have always and probably will always be a thing in an RPG since there most likely will be an optimal skill order to use to do the most damage its just that a lot won't tell you the exact rotation (though 14 doesn't really tell you outright what the rotation is so eh)

It's mostly the melee jobs who can get away with a condensed combo system. Most of their stuff doesn't change. At all.

DRG can do it as well as Wheeling Thrust / Fang and claw aren't random anymore

True > Vorpal > Full Thrust > Fang and Claw

True > Disembowel > Chaos Thrust > Wheeling Thrust

All of the melee AoE's can easily be made into combos as well.

Tanks are just a 1-2 comb on each one.

DRG is a 3 step combo that doesn't change.

SAM is a 2 step that changes a bit but can easily be made into a 3 step combo. (Fuga > Mangetsu > Oka gives Getsu then Ka)

Ninja is a 2 step aoe combo that doesn't change.

MNK is now a 3 step aoe combo that doesn't change.

The point is, all of these jobs could easily gain 4+ free slots that could give them back old abilities or better new abilities.

At the end of the day, Job button culling is going to happen. Square makes it evidently clear not just in practice, but Yoshi-P himself has said passing quotes on the matter that they desire every job to be within a certain range of buttons. So the options are to let them condense rotations to hopefully avoid them touching actually interesting parts of our kit rather than the utterly mindless, mechanical, every player will have forged into muscle memory and never have to pay attention to part of their toolkit, or we keep combos uncondensed and it's guaranteed OGCDs and actually interesting parts of our toolkits will be getting cut.

Pick your poison. I'd rather they get rid of pointless bloat so that way there's a chance we don't experience a SHB 2.0 with job gutting.
