People will always stand in the fire. The best thing to help players out is when someone in the duty group takes a few secs to explain things. I was gone for about 6 months. Came back and before I had to leave I was stuck on the Dark Inside. Every group would wipe 4-5 times and people who had finished it would do nothing but yell. I came back a few days ago. Got in it and we wiped 1x and someone then did a quick explain and marked themselves for us to follow on the move mechs. That would be more helpful imho then anything else. In SB I used the trust system to learn the mechs of the duties before I joined lfd groups.

A little kindness in the groups goes a long way also to help players. I know a person who if they get yelled at in a group for missing a mech they purposely miss it. That's not right but they do.
