Everyone has their own ways of enjoying the game. I just like grouping and helping people get some nice gear. Most groups I have been in (Pick Up Groups) have been Need Before Greed. Sometimes I've been in on greed rolls for all and I personally have never liked them. It's usually a good idea to ask if the group is greed or NBG so that you can set your expectations correctly or pass on the group.
I understand why people want to greed roll on everything; because it helps them get plat to get gear for their characters or to use on their alts. I have alts that can use all kinds of stuff but I will gladly hand an item to a class present that can actually use the item as an upgrade. I have always viewed this from the perspective of "if I were that monk and the pipe dropped in KC or the T Staff dropped and it went to someone else in the group so they could sell it, how would I feel?" Again, it's all a matter of personal play style and motivations. Everyone is different..
You should get in a guild where people help each other out with gear and avoid Pick-Up Groups where possible. This way you get maximum enjoyment out of the game.
