It's more about the fact that you know immediately if a healer or tank isn't doing their job but a lousy DPS can take a lot more effort to unmask.
When there are 4 DPS in particular, you'll have to watch ALL of them mid-fight and then check their gear one at a time as well.
Again, compare this to tanks and healers where it's infinitely easier to know who is causing wipes.
I started this thread because I was in disbelief at the hypocrisy of the community regarding how we treat both tanks and healers vs. how DPS are treated. It's sickeningly hypocritical that tanks and healers can be kicked after a single error (I've seen it happen) but DPS aren't subject to at least the same level of scrutiny for their performance.
But more and more, I've realized that the whole parser debate is a symptom of the true problem, and that is that XIV does a horrendous job of teaching DPS players how to play their classes effectively.
This wouldn't be THAT bad, except for the fact that the game features DPS checks in content that is far from savage raiding.
When designing any game, the #1 priority is to teach the player how to play well enough early on that they are prepared for the challenges they'll face later in the game.
With DPS checks in the game, it should ABSOLUTELY be teaching players proper rotations for their class to ensure they're able to meet these DPS checks when they encounter them, but no such training or tutorials exist in game that do this.
The end result is that we get DPS players arriving at endgame with no clue if they're doing even marginally well at their class, as well as no guidance on how they might improve.
There should 100% be an NPC called the "Battlemaster" or something that the game directs you to upon reaching the level cap, where you learn the rotation of your abilities and how to be the best you can at it. Not that this forces the player to BE the best before they can complete the quest, but it would at least show them the path to how they can do so.
Some part of me wants to slap together a video tutorial for some DPS classes, but aside from not having the time, it wouldn't change anything because we need something IN-GAME that teaches people...
