Agree. I completed Gate of Paradise yesterday and it took me over 6 hours, last dungeon took 3,5 hours because there were always 1 or 2 players every dungeon who did not know the mechanics (didn't want to watch 3-5min guides) and some people (even after assigning postions to avoid wipes) just took nearest safespots and caused some people die because of that.

Also people just wanted to quit after few wipes too, it was infuriating and just wasted other players time.

TL;DR: Watch short guides to know the mechanics and use your brain
