With the patch I feel they should rename the rarities. Yellow items can be hardly called Rare now as it's the stuff that drops all the time. It's interesting as white items are quite rare now which is funny, blue drops from act bosses(lol) and sometimes from chests/etc. Legendaries should be called rares now imo, atleast in my games their drop rate is indicative of that. And I'm not sure I ever saw a grey item since the patch.
