Much better option, particularly in simple dungeon content, is "Hey, I'm only i80, and I see you all are in Ironworks/Dreadwyrm, other person of my class. Should items drop, can I have them?" Most people agree, and I've seen dungeons where everyone just passed on EVERYTHING for a polite lower-geared player. Of course, if someone says "No, I need gear too, for (seals for relics, Desynth, glamor)" then you can't get mad. That is a valid play style choice. I will say I tend to call out people who need on pink items in 15-45 dungeons when someone in the party could actually use the upgrade, cuz the seals are trivial, the glamor can be gotten cheap, and there are better desynth options.
