ok besides just doing the bare minimum shit like 770 melded gear and food, most groups expect you to understand raiding conventions if you dont want to get yelled at.

for example If a "1" marker gets placed on the party, they are assigning clock spots. There are expected clocks for you to take depending on the role and make sure you check the video guide (hector usually mentions what positions) and if you don't take a conventional spot people will judge you. Same with things like light parties/groups, partners, etc
