"But i have to say there are a lot of really nice players who volunteer to give others the loot they win if it is a duplicate or they see someone who really 'needs' it. I gave a nice Rogue in i360 stuff a token i got. I figure what goes around comes around!"

This is something that I do. I know there have been threads where people look down on this with the reasoning that I'm circumventing Blizzard's loot policy to 'play god', but there's game theory happening here that says what I'm doing is for the best. Me rolling Need on gear I don't need in order to hand it out gives the underdog a better shot - in essence I am defending myself and others from those who are going to roll Need on everything - to troll, or to vendor.

I will say however, that I also roll in order to trade with people, and I think this is completely justified as well. Everyone put in the same amount of effort, therefore is entitled to the same amount of gear regardless of personal situation. Obviously other people in LFR don't care if I 'only need Will of Unbinding', so this is a fair and effective defence.

True, and if you have several toons your run RF with it can get crazy remembering what each one has or needs, even with an auto roller, so sometimes you get a duplicate and it is only fair to let someone else have it if they really need it or forget to roll need. It isn't like you give it to them for gold, unless they are on your server and you blackmail them or something lol
