this must be an FAQ/noob question but is there a setting / way to get just the greens or maybe even just the blues from a run; without opening each corpse ? (or maybe with opening them but not actually looting unless there is such green/blue (like having the roll window open and watch that and ignore everything else; yet when there is a stack of mob, be sure you didn't miss any - hopefully you guys can guess what I'm trying to say; it's a bit hard to express)

in short what is the fastest way to run through an instance and ideally have a single char get all the greens/blues without actually looting each corpse - or best alternative that is quick but doesn't miss on blues ?
