When I started the game, I had a lot of random higher levels join into my instances and run through, helping me. I recently hit 50, got somewhat geared up and figured I would return the favor by helping others. Tonight, I was running a group through some of the lower levels and after about 4-5 different levels a Rare Pink drops (valued around 100k), of course with my luck, it didn't go to me, and as soon as this guy gets it he leaves the group. I message him and ask him if I can have it, since I was doing most the work, and I could use it on one of my twinks. Well, needless to say, I never received a response, but not more than 20 minutes later, I see it in the CS.
So, along with me ranting a little bit, and deciding I am never running a lower level instance with a pick up group again. What does everyone else think about this? Is it just the way the game is played, or are some players actually honest and not concerned only about their own greed?
