Got a 310 chest piece... I had one already from the normal mode and two exotic chests at 310 as well. My personal opinion is that hard mode should not drop anything lower than 313 anything else is just a troll drop. Or you should be guaranteed a armor or gun drop between 310 and 320. If drops weren't so occasional I wouldn't mind drops at the bare minimum but to do the entire normal mode for a 300 ghost or to do hard only to get one or two 310 drops is a pile of crap.
