Would you be opposed to SE implementing a program to scan for addons/parsers?

1. First of all, it isn’t only my way of playing the game. The devs of the game clearly don’t want players to use these tools especially in PvE, because they create an unfair advantage. So if somebody clears an Ultimate with these tools and apparently thanks to these tools, they have not cleared the content as intended by the devs. In a sense they’ve cleared something else.

2. Most of the time, what wipes parties in FF is not DPS checks, it is incorrectly solved mechanics or standing in an AoE. Therefore using DPS meters brings no value to the fight. Regarding other tools, like zoom hacks and mechanics solvers / announcements, I stand by my claim that people who need them, are not playing the content as intended and are missing the entire point of high-end content in FF14. Which again, is not about DPS, but about solving mechanics.

...okay, enough of this please.

If you are going to start debating on this topic, at least make sure you understand what actually is being used, how it affects the gameplay and whether or not led to the current problem. You and everyone else.

1 - Parsing does not create an unfair advantage*. What it does is present numbers to you. The issue with parses that makes them illegal isn't the fact that people can know numbers or not. Those numbers are available on the Battle chat, so if anyone collects it, runs it through excel and makes a graph, it might take a long time but it's still going to yield the same result. What makes them legal is that this information is being accessed directly from the server and calculated in real time. And there's a potential danger that it can then be used to harass others on the spot.
FFLogs doesn't give anyone any upper edge. All it does is take all that data, whether from Excel or from ACT (but since ACT is a lot more standardized and less prone to mistakes, that's what they'll take) and make it public. The illegality here is having in-game stuff being made public outside of Lodestone, and again the aforementioned potential danger for harassment.
*You can argue, however, that the advantage exists against Console players, which is a correct statement to make. But the use of parsing alone does not mean you will have an advantage of clearing the fight, which was what you're saying.

No one clears Ultimate because they know how much the Bard dealt damage. That's not how it works.

Stuff like Cactbot are things attached onto ACT which give out call-outs by parsing server information. That is an advantage.
And what led to this particular Ultimate being cleared were people using zoomhacks to get information that wouldn't otherwise be displayed to them in full. That is an advantage.
Same for UWU whose script was datamined and later used to clear the fight. That was an advantage that people who got that information had.

ACT doesn't enable datamining or zoomhacking, but does enable Cactbot. Not by default, however, and Cactbot needs to be programmed to work out the fight. So the fight needs to be cleared first so Cactbot is then fed.

People who parse aren't cheating just because they parse, they're just being fed information that would be monotonous otherwise to obtain.
Prior to 6.3, you could argue "Ah, but they're getting information on which hit is magical or physical". That advantage no longer exists.
You could argue "Ah but now they have a more accurate timeline of the fight", which sure, but they won't be keeping track of time. To do so, you'd need other tools than parsing. And at that point, you're already going outside of parsing altogether. Not everyone who uses parsing tools does this, and to claim that they do is just unrealistic and fearmongering.

What led to this ultimate being cleared was Zoom Hacks. Not parsing. It never was parsing.

2- Failing DPS checks is too broad a thing to point out, you know? Because if the majority of the party is dead or has died recently and has the penalty, they will not get enough DPS in the long run to clear things. And nothing kills more people than mechanics that weren't properly executed. So one leads to the other: both statements are correct.

And the people who are using zoomhacks and call-out bots like Cactbot inherently are cheating anyway, so...
