Hey OP, I was a former ps4 player.
Been raiding since T4 was a thing, back on my PS3 then switched to PS4 from T5 to A8S.

Some of the most frustrating times I had was leveling new classes. I couldn't see if the opener I was doing was ok, I couldn't try new things because I had zero point of reference.

I didn't know if I was contributing meaningfully to the group dps in content. I'd ask for my parse after every fight during raid. Also during raid, I couldn't see where I was losing dps so I couldn't see any parts of the fight I could improve on which was especially rough in Gordias.

I was lucky enough to get some $ for a gaming PC so I switched. I will never go back to PS4, ONLY because of my parser. I do not find playing a "blind" dps fun. It's allowed me to literally get better as a player.

So yea, I agree with you. It sucks for PS4 players, it really does. I genuinely hope some sort of meaningful meter is installed in game, whether it just be on a target dummy or not.
