Valefor spawns bugged?

[GSGregory]

Valefor either has insanely low spawn rates or spawns are bugged. I am currently writing this as I attempt to play this mission and in the two minutes or so now since starting an extractor I have seen no more than 10 enemies total and only one power carrier. It is near impossible to play this mission solo. Tried playing it with a friend last night and it is barely any better. Just gave up on the mission after 3 minutes of no power carrier and no enemies. 

 

Something is very wrong with this mission if enemy spawns are grinding to a halt and you simply stand around hoping for the next solo enemy to be a power carrier.
