We're looking for confirmation on either our bad luck or a potential change in drop rate. After killing named mobs in VP for six days we've noticed that power sources do not drop as commonly as they did about maybe about a month ago. Specifically we are killing the five 90-minute named mobs. We do 2-3 full clears a night and have noticed a drop rate of about one power source per 2 full clears. We have yet to see the caster power source at all in that time. About a month ago we had 2-3 power sources per round (of five named mobs) of all kinds of power sources. Are we that unlucky or has anyone else noticed this change in spawn rate? Thanks.
