Why doesn't pve have pvp combo structure?

[shao32]

having to press diferent buttons for 1 or multiple combos add the risk you fat fingered or you hit the wrong/same key making you break you combo and probably mess with your rotation a bit depending of what job are you playing, having everything in 1 buttom you literally remove that factor and it's simplification since it literally makes the player reduce the amount of diferent buttons they need to use to execute they rotations so yes it makes the game easier.
