Just give us a list of what addons we can use.

So wait we'd never improve without those tools? I'm getting confused. I was lead to believe the content was designed to be beaten without a single third party tool and that includes ACT. Yet here you are telling me that players as a collective would never reach a level of doing so without analytical tools that let them pinpoint basically everything much faster than we'd do it without them? Is that how entire getting better process look like? Check the numbers, throw the log into analytical tool and do what it suggests? Now I question if I even want to reach that level

This isn't how these tools work. FFLogs/ACT doesn't make suggestions, and XivAnalysis' suggestions are seen as virtually useless at the high-end. Most of the actual 'pinpointing' that is actually important comes from reviewing VoDs. Combat logging is more important from an optimization standpoint, where you're able to more conveniently review and share player ability timelines and statistics. Calling it a crutch is akin to saying a business using graphs to understand and improve their sales is a crutch.

Where are all of the top-end players that supposedly don't use these tools? Why aren't they coming out and making statements against them? The top players of this game, across all regions, make heavy use of programs like ACT and have done so continuously since ARR. Virtually every piece of information any player has taken from sources like The Balance or AkhMorning has been produced with assistance of these types of tools. The entire identity of the game, and the way the players play it, has been actively shaped by this for like 10 years. Content is designed and increased in difficulty around player capability. DSR was made more difficult due to the ease with which players devoured the last Ultimate. The developers couldn't even beat their own ultimate without adding additional checkpoints.

As of ACT wasn't one level of outrage coming from the fact that World First group used automatic call-out they programmed into their software?

We're talking about the analytical purposes of third party tools here, not automation. That's an entirely different can of worms.
