Stone, Sea, Sky is the closest we'll probably ever see to a parser in game, even though it completely screws MNK now due to Brotherhood.
I know people in my FC that do parse runs (I'm on PS4 so I can't check myself) but it just feels weird to ask for a parse, just to gauge your own personal performance and while they said I did great for my MNK (3.6-3.7k in V1S in i320 gear at the time) without any context about the number, I was still just as clueless on how to improve short of getting better gear.
