Why is it so common to join extremes without watching a guide first?

[SturmChurro]

If you want to do a blind run then join and say that. Don’t join and ask for the full written guide when that is accessible literally everywhere online.

A lot of players are probably used to someone literally typing paragraphs and explaining fights. Others are likely afraid to admit it's their first time, or speak up in general.

Next thing you know, they show up in Duty Complete Farm parties STILL making mistakes like they never did it before.

That's exactly what happens! It's why I get burn out trying to do extremes every expansion. So much wasted time just trying to find a party that can clear in something literally labelled "farm"! Even inside the instance, someone can ask whether anybody needs some help or a refresher with anything, and nobody will speak up, then we wipe, constantly..
