This is a combo noob, WTF moment.  When i was still lvling my warrior, i was running RFD and a nice set of boots drop, think they were mail.  Anyways they were a huge upgrade over what i had so i asked if i could need knowing that nobody else in the group could use them.  Two of the guys say sure, so i need.  Right away our priest gets pissed at me, saying he wanted them also and how dare i need anything in an instance.  He then emotes on me several times, curses me out, then leaves the party.  Everyone was like WTF is his deal !?!
