To be fair though, since most of the playerbase has been playing for 10-15+ by now it does get annoying when someone apparently still doesn’t know the mechanic(s) in some of these 15+ year old dungeons
It’s not really a “being mean” thing, but rather a “being annoyed” thing when the content/dungeon/thing in question has been around for 15+ years but someone apparently couldn’t take the time to do a basic Google search… assuming they couldn’t figure out the mechanic(s) just using their eyes and ears (for example, ignoring/getting hit by an “obvious” swirly that spawns under them)
Even for the 15+ year old content/dungeons, the mechanics are often sooooo obvious that even without Google or using any automated addons like DBM you should know (just via common sense) to avoid or quickly step out of the “bad”/fire patch/poison patch/etc as there’s usually a 2-3 second delay between it spawning under you and the damage ticks beginning
