Why do people not understand...we are only a week into the new content?
There aren't even visual guides out yet for anything, and we all know that only a very small percentage of players seems to be able to read written text
Failing is normal, just because you wiped yourself through your first clear doesn't mean you have any idea what to do. At this point I'm not worried yet about having to explain mechanics and the like.

Now of course it is different when you make a pf specifically seeking only people who know what to do.
I was on the verge of getting mad today when I made A7 parties (because in about 20 rolls, a 7 was the highest I ever got on that stupid spring >.>) specifically only with experienced people who know what to do and can easily farm it...and then you get one dps after another who attacks the lock in the heat prison and dies, one healer after another who just stands in the healer prison, blandly staring at the party dying to horrific poison, tanks who never move the boss and think dps can kill the heart on time when it spawns IN the boss...and so on.
I literally had one person who thought "oh, prison mark! I need to share this with the others!" and ran into the party to get 5(!) people into prison.

And you complain about A8 pug groups..
