Not really sure what they did, this was a bug since the patch, but something seem to have happen. Since the patch I found only 3 level 61 items, until now! Currently running act3 on normal to get a waypoint in act4 and since I started I found so far 14 level 61 items.
If this is even useful, im not sure really, but something odd do happen in act3 normal for me (In the keeps)
