Although I disagree with the concept that you can easily tell how tanks and healers are doing without parsers, I agree that DPS are often the weak link in a party. I think SE is the one to blame because there is no way to tell how you are doing comparing to others without a parser, especially for DPS players. Everyone will assume they are doing just fine, above average even though they are actually bottom dpsing by quite a bit. For most of the content it doesn't really matter what dps players are doing, you can clear it eventually. When it comes to extreme and savage, things get different because there's an enrage timer. You may have all mechanics done right but you still won't be able to clear it.

Here is where the situation get tricky, SE introduced an in-game dps check without an in-game dps meter. This is completely unfair to new players, especially the ones play on console. Because as a new player, you might just want to try all the content in the game. And when you do, you get shamed and booted from the party because of "poor dps". I've seen so many people doing questionable dps for all 3 roles. And to be fair, the game doesn't ask you to do SSS dummy fight, gating the content behind it won't help either because putting your rotations into practice is another story. Not to mention how badly tuned some SSS dummies are (NIN require almost same dps as MNK while MCH's dummy isn't tuned after receiving several buffs).

I disagree with "parsers create toxicity". In fact, by adding in-game parser in the content where dps matters, I believe it might fix some issues the game have right now. For example, with the in-game parser you can check if you are ready for clearing the fight both dps wise and mechanic wise, then you can join a clear party. And when you are in a clear party but there are people who are not good enough for the clear, vote kick them then re-recruit. Some people think kicking people for dps is toxic behavior of elitest, while I think the people joining the fight which they are clearly not ready for and whine/report/blacklist for being kicked IS the toxic one. Sure there are people expect speed-run level dps, but you can avoid most of those parties by reading the recruitment condition or even create your own party. And there are very few "top-tier dps meta comp only" parties on PF, at least on my data center (Gaia).

The point I'm trying to make is that all players need to/deserve to know how they are performing. So they will know what content they can do at the moment, more importantly, how should they improve to do harder content. And people who deserve the clear can clear much more easier through PF. If you want to argue that you can form/join a static for that, I would ask why should I if PF is good enough. Are you the one ruining a party? Or you support that kind of action? The mindset of "As long as I'm having fun it's okay and you don't pay my sub" is just beyond stupid. Who are you to waste other 7 people's time? Do you pay for their sub? Do you pay for their extra effort to clear with you? Are other 7 people having fun? Like seriously, bad players need to improve and new players don't deserve to suffer from SE's stupid decision.
