Didn't even know FF14 had a mechanic callout helper till this thread lol. But y'all do realize most if not all other MMO's have community sanctioned and widely used raid addons that popup warnings on screen for upcoming mechanics, right? Fighting with yourselves on a forum over how terrible and evil such a thing is, is truly a FF14-only concept.

Also it's not exactly some nefarious James Bond badguy supercomputer conspiracy to figure out that an upcoming mechanic is gonna proc 2.5 secs after a boss hits 35% HP or whatever. Whether a popup on a screen tells you that or you are REALLY good with a stopwatch and mouse in your hand, you look ridiculous fighting over it.
