FFXIV originally had a Skill chain/Magic burst system where you stacked up actions and then released it. I forgot the name of it but it was really awful and unintuitive, and it also prevented you from doing any further attacks/actions until someone triggered it.
The combo system they replaced it with when they added auto-attack was much better, and the limit break system looks way better as well.
Edit: I remember now. It was called Battle Regimen.
