Why doesn't pve have pvp combo structure?

[Ultimatecalibur]

DNC: first two stages of their combos can be condensed. If the code allows for it, 3rd stage hits could be condensed as well.

I agree with what you have said but feel DNC is a job that that won't work for as Cascade/Fountain/Reverse Cascade/Fountainfall convert into Emboite/Entrechat/Jete/Pirouette during Standard/Technical Step. They can't be compressed into 2 buttons because they are already 2 mutually exclusive sets of 4 buttons compressed into 4 buttons.
