Why doesn't pve have pvp combo structure?

[ItMe]

Next people will be asking "why we can't just automate the game".

Players have tried to macro their rotation for a loooooong time.
Part of me feels like this 111 idea is a compromise of sorts, but ultimately I find this topic interesting because of the discussion it's hovering around: which is more valuable, executing a more complicated rotation or executing more complicated mechanics.
