Yes, I tried to pay it forward since when we first played, there was guy who ran us to deadmines and gave us bags. I would even give suggestion to what class they should try instead. I always feel that rogue and warrior are probably one of the class most new people would struggle with if they were never a gamer. I HATE running people to dungeons. My husband made me run him to Stockyard over and over till I FELL ASLEEP. I am not kidding. I leveled the fastest among him and friends and stuck at running them to dungeons and the worst is, they leveled so many characters,so I had to run their alts too! So I got mad one time and said no. The most I'd do with newbie would be to buy them bags,I think bags are so helpful when you start playing. And in populated server, they can be pretty expensive especially a 24 slots one.
I don't like that type of new player who rely on you. Too scared to do anything else without you and too lazy to queue dungeons. I try to avoid them.
