To net it out, bonus magic find just for hitting patch and the ability to farm Acts I and II in addition to Act III. Act IV due to size is probably still not efficient / viable. Extra bonus of Infernal Machine stuff -- only have 1 key so far from Act III (had maybe 2 or 3 stacks of Valor when I got it). Also came across Act II warden by no drop.
