Here is a possible senairo (something that really happen in ffxi)

your in a group with a healer, he is a dad with a 7 year old. And is only one home. 7 year old starts choking on He told hos party g2g, party forces him to look for a rep. Guy says he can't, leader starts bad mouthing the guy. While the dad was typing kid collaspes and later dies.

The time it took him to type out g2g was time needed to save the kid.

So ya real life over a game. If you have a issue, just remember this is a video game. The players your group with have no strong connection to you in emergencies. And in most cases have no time to type g2g and drop.

Think about that next time you try to insult an "afk leecher". You do not know the full story.
