Common Courtesy: If someone is inexperienced, tell them how to deal with the threat ahead. Pass your experience onto them. They are part of your team, if they fail because they don't know the fight, you failed them because you didn't explain it. It takes like no time at all to explain a fight as you go along. really it doesn't. and for anything that might need explaining a macro helps too. I'm not going to spend time in the game, only to spend more doing homework on it later. Killed Titan and Caduceus without videos, because my FC isn't full of elitists that expect everyone to know everything for the sake of a quick run. If you don't want to end up in the duty finder with people who might be inexperienced, how about you preform a party instead.
