For the first point, i think you're decked in really good gear, a wizard friend which farms T6 pretty easily is not finding anything worth because he simply has godlike gear.
For the second, that skill is used by a clanmate and in party/coop is a huge buff since 20% more damage for everyone is really strong. He's running a fire build running away from the old one and he has no problems in farming. I think he would really like to get that item
EDIT: i dropped the new natalya's ring - holy hell it's awesome, especially for set bonuses. I cannot wait to get other 2 pieces - dream list would be boots+weapon and the lòegendary cloak for triple wolves
