I will not say the current combo in FFXIV is the same as Aion

You do Featherfoot to boost your evasion to have a miss in order to beable to use Simian Trash, this is a tactic not a combo, because you simply can use Simian Trash whenever you evade the hit and have 1,5k TP

Aion Combo Might sound like unlocked but it is only half right because this is a mmo and not reality if you compare in this way:

Aion: Left swing -> right swing -> Smash down (chance for knock down) -> knock down -> Finish Move -> end of combo

Combat game: left punch -> right punch -> mid kick (target dizzy if hit) -> dizzy -> Finish move -> end of combo

in FFXIV the LNC skill with the long animation with multi thrust is just like the Aion skill from Left swing to Finish move but in 1 button while at aion, they seperate that to 4 click and 1 requirement and make it look like it s unlock

feel free to keep disscuing, this thread is interressting

ninja edit: if we talk about battle reg it ll be different because battle reg is party combo, while Yoshi mention is solo combo, those 2 cant be call alike or can bring out to compare
