It's not false. People choose to use parsers. They don't have to use them. It's a choice, not a requirement.
Saying "EVERY!!!" top group has used them is just argumentum ad populum.
It also implies so-called "top players" aren't good enough to defeat encounters without add-ons/3rd party tools to help them. You're implying they need a crutch to do so. You're implying that relying on their own skill, knowledge of their given role/job, ability to coordinate and communicate, and learn the mechanics through trial-and-error, isn't enough; they still fall flat. You're saying every (EVERY!!!) top group isn't quite as good as they seem to think, since - according to you - every (EVERY!!!) one of them requires add-ons to clear it.
That's effectively what you're saying.
Not very flattering! I suspect some in the end-game community would take exception to your broad-stroke characterization of them.
You mean what the PC players have had the ability to do unofficially, on the down-low. You're talking like parsers have already been officially sanctioned by SE and are considered legit, but just haven't made it to consoles, yet. You're talking like number parsers are something Yoshi-P has officially spoken out in favor of on an official level. He, quite clearly, hasn't. Again, you seem to be arguing from this position of "Well, people are already using them, therefor they're necessary, and everyone should have access to them!", while ignoring all of the facts that clearly run counter to that. Your argument is pure confirmation bias. Unfortunately for you, ignoring readily and easily verifiable facts, however inconvenient they are to your narrative, doesn't make them go away.
I love this attitude. It boils down to: "Jerks will be jerks regardless, so what's the difference if we give them one more way to do so, eh?"
Of course, in your case, "... as long as I get what I want!" is appended to the end of that statement.
I mean, after all, as long as you get what you want (an official parser), then hey, you'll just accept it as a necessary side-effect, right? Let others deal with it. You, and/or others in your camp will be too busy obsessing over others' parser numbers to see who the "bads" are to care!
It's also plainly hypocritical. You people are crying foul about not having something the game has never officially supported, and that you do not need to clear content (unless, again, you're not actually as good as you want to think), and consider it some great injustice. Yet you turn around and are basically "pfft.. whatever. Others will work it out" about the fact that the inclusion of said thing would empower people to become even bigger ass-hats than they already are to people who are just trying to enjoy playing the damn game.
Your priorities are backwards.
Every single person paying to play this game has a fair expectation that they should be able to play the game as they like, at their own pace, and enjoy the experience within the confines of what the game offers and supports. Conversely, you, and others in your boat, have no legitimate expectation that the experience must include an official parser. In other words: Your want for an official parser, something you have absolutely no reasonable expectation of in FFXIV (it's never been promised to you), is not more important than others' desire to play the game and experience it without unwanted harassment from people who think it's their place to impose their playstyle/preferences on everyone else, "because numbers".
Per Yoshi-P - in his words, and actions (SSS) - it's not going to be officially part of the game any time soon. He's mentioned that when player add-ons become a thing, that players will likely create them. And you better believe he'll be keeping an eye on how that data is used/misused. His decision is not made lightly. He's explained his position on this subject. He's expressed his fears, which stem from the fact that when players have access to other people's combat data, it tends to get abused - a lot. That's the reality of the situation. He knows it. I know it. And you know it - though you readily dismiss it. Coming here and talking about "well PC players have already been using them, so console players should have access to them too" only demonstrates that you are completely and utterly indifferent to the reality of the situation. Again, you want what you want, and that's all that matters to you. "Everyone else can just deal with it".
And all because some people are - again, literally - obsessed with numbers... especially others'.
You can spin, argue, dismiss and try to rationalize it all you like. There's over a decade of evidence, across myriad MMOs, where many people will take parser data and use it to bludgeon other players, for no other reason than "because they can", and feel they have the right to. Yoshi-P - rightfully so - does not want that crap in this game, any more than it already is.
And again, if you don't like what I say about that group of people... don't get mad at me. I don't make people act the way they do. I'm just pointing it out. If you want official parsers to be seen with a more positive attitude and more accepted... turn your anger on the assholes in your own sub-community who abuse them, and ruin it for everyone else. If you want to see a difference in attitudes towards official parsers, don't go after the people voting against them. They have over a decade's worth of reasons to. Go after the people in your pro-parser group giving them a bad name in the first place.
