If SE is worried that parsers will be abused in order to kick underperformers from a party, why can't they only make your own numbers visible to you? All of the numbers are already there, logged in your battle window. Is it that difficult to implement a program that does the math for you, and averages your DPS? Maybe a toggled stat display window after a dungeon clear, similar to the ones in older FF titles?

I honestly don't care about anyone else's numbers, but I'd like to be able to see if I'm pulling my own weight, and figure out where I need to improve. I'm on the PS4 so I have absolutely no way of knowing, short of doing all the math myself, which is just tedious. I can't even toggle flying text to own show my own damage in order to keep track that way.

I don't think this is unreasonable. No one can improve if they can't even see that they're lacking. And more softcore players might not even bother, so a hidden toggle window shouldn't be too intimidating for them.
