parse for ps4 users !

I haven't been in many groups where a 'DPS check' not being met was the result of someone slacking. I was in some of the early Alexander runs and there were a few where we wiped to Self Destruct, but it wasn't because of slacking. At least, not outright slacking. Sometimes one DD would be left with two spiders while the other DD on that particular boss just kept wailing on the boss, causing that one DD observing mechanics to get Mini'd. Or the one holding the spiders would receive the blessing of RNGesus and get bombed while trying to kill the spiders. Generally, shit happens and you have to look at the fight from more than just the angle of the 'DPS check'. I, personally, never give up on a fight until everyone gives up and by that time, well, everyone's given up so there's no point pointing fingers at anyone.

Of course there can be various reasons why a DPS check failed, it doesn't have to be someone slacking.
But even then, a parser points you into the right direction.

When My FC did Bismarck EX for the first time, we noticed that one of the BLM was doing rather low DPS thanks to a parser (he didn't notice). It was because of mechanics, not because he didn't want to perform, so we gave him pointers, where he can mostly stand in one place, and it went way better (we didn't clear in the end because we failed 3rd phase, but at least we got to the 3rd phase...).
You can't notice stuff like that without a parser.

Or lets say you fail Faust in Alex Savage, that's a DPS check that has ZERO mechanics, you just stand there and beat on him. Without a parser it's REALLY hard to see who needs help (be it more optimal rotation, better gear, or buffs).

Or lets say you are playing AST - Balance is % based, so it's worth more to put it on the player who does the most DPS. How are you supposed to know that without a parser? Keep in mind that the difference can easily be more than 100 DPS, which can be "make or break" in many DPS checks.
