Extremely low rate drop at Udas and Lower Udas temple

Have been doing these instances for days 2 times a day (minimum) and all bosses have bad drop rates, anurati wont drop eternals and most times he wont even drop fabled armor. Nexus and Vallkhan have a really low chance to drop fabled armor. At LUT Bergisar and Kingpin wont drop fabled gear and Debilkarim will drop eternal gear more often than fabled. BT has a better drop rate than these lvl 52 instances.
