I agree with some of this and disagree with some too. I don't think dropped items should be shared nor do I think every chest should have uncommon gear. However, chests should have items scaled to the lvl of the player who opens it. The item might be a white item, but it should be scaled to lvl 8 if I am lvl 8. For instance, I found all of the golden chests just to find gear with stats significantly lower than my current gear.
