You don't have a single job at 80, so I am going to try to explain why this dead horse thread is amusing. Cactbot runs on reading out the script of a fight. This is already written out and understood by anyone going into Savage pretty early on. Generally after week 1, but sometimes it takes a bit longer. Cactbot is unusable in this time because it depends on this timeline, so these "World Firsters are cheating!" is not true. They usually publish the timeline themselves.
Just posting the link here, because the image is actually pretty large.

This is the timeline of P1 for E12s. This is how the fight will play out every single pull, and without exception besides the absolute nuking of the boss.
This isn't WoW. There is no magic DBM that gives you markers and individual callouts over your head. This oogey boogeyman is an annoying TTS reader that is more obtrusive than anything else, because players making their own callouts will be drowned out. Because it is a simple TTS program, it cannot ever change for RNG, unlike DBM (which people in this thread seem to be more familiar with). DBM is a way more sophisticated program that Blizzard basically made mandatory due to not designing well structured encounters.
Is there some benefit to being alerted to a mechanic? Not any more than just having progged it, and the fight becomes monkey-brained muscle memory. TTS isn't going to help you clear the content. If someone can't clear, then using Cactbot isn't going to help because there is a deeper issue at play there.
