I don't know about you, but for me; I just have to respond when I see people say LFG <random group quest> in general channel.
This spurs from the time when I was leveling and there was no one to help me.
People just don't want to do it when they are not on that quest. But I'm glad when I can help because I know that I just saved them hours of LFG.

So do you help people in their random time of need?
