If he's running heroic, then yeah likely his save is screwed for the week. But, I can also understand needing something like say one of those fancy socketed rings, seeing one of them drop and wanting it, just to kinda get bait and switched by getting kicked out. Not only does it really frustrate you all in all, but that also means the thing you wanted you will have to wait at least til next week to drop. That right there would screw my entire week over if something dropped for my toon and someone just said "lol" and kicked me.
