As of the new patch implementation they're claiming to have entered something called "smartloot" which basically gives the loot rolls accordingly to your class / stat orientation so you can grab better gear faster, however after I've played the PS3 version where this was present since the beginning, and now playing the PC version with the patch that introduces this, I can tell at least in my opinion that the loot is still pretty bad, despite the rolls being a little better in terms of basic stats, but it's still hard as hell to grab a nice piece of gear if we compare the time spent with the ps3 version..
Let me know your thoughts on this.
