How would an optional, official parser be toxic?

[Sigma-Astra]

A person who doesnt bother to improve his gameplay will not magically become better for having a parser, similar on how people dont play tanks despite all the bonus they keep putting for playing as one including faster queues, exlusive mounts, role bonus etc.

They may because they'll actually see how much damage is inflicted depending on how well or how poorly they're timing their cooldowns and rotations properly, for example, holding certain abilities back INSTEAD of wasting them during phase transitions for a boss.

Thats not a person whos learning his rotation, thats a person whos pressing buttons randomly sometimes without even bothering to read the skill descriptions. Everyone has had those kind of players (thanks god not very often) and you dont need a parser to know they suck (comes to mind a lv 70 Dragoon spamming impulse drive ONLY, or a Pala spamming Rage of Halone without the proper combo with aggro all over the place because not only aoe was too advanced for him he did lose aggro on single target as well) and if they didnt even bother to read what the hell their skills do, parser wont do anything for them to improve since theres 0 motivation to do so to begin with.

Gee, wouldn't it be so great if like, we had people who knew what they were doing that we could reference the right rotations...and see how much damage they should and could be doing when playing optimally on certain fights? Oh....right.

We do. It's called FFLogs to find out which people are the solid players that you should measure yourself by.

You know....that tool where you can see how many times they've used what, when, and where....the tool that lets you playback the fight in a very basic, but kinda helpful way?

Gee, wouldn't it be SO GREAT if people knew that doing their rotations out of order ACTUALLY hurts their damage? What on earth could measure that, I wonder....
