I have Ilv.90 gear as Tank and i do lot Need on gear of lower Ilevel... becuz i actually need it, as OP state, i use it for GC seals, thats my reason, if you really did NEED tanking gear you should be the Tank and you should get it without troubles, so whats the problem here?

Ok lets say im a DPS MNK in full Ilv.90 gear and you are a Ilv.45 MNK , we both cast lot NEED on a Ilv.50 armor, it seems fair to me in the way we both can cast NEED on it, leave it to luck who of us get it.

Your reasons and my reasons for need it can be diferent, be it to wear it, collect gear for glamour or to sell for GC seals or w/e else, the point is we both need it, if a person NEED it instead GREED it is becuz is doing the instance as such class and this allow him to NEED it for wathever reasons it be, this is fair enough.

An analogy to this be, "what you need money for?", so a person who is rich and worked hard to earn his money has no right to it when compared to a Poor person?
