As far as i can tell from yesterdays session they just pop up like normal nhss. If you find a lvl4 nhss, this has so far always been 4-5 marauder scouts in my experience. I dropped in to many lvl5 nhss, they always contained a cyclops as normal.
I did see a lvl8 nhss, just had to have a look at that! I dropped in, there was some form of interceptor there (which instantly waked out), and 4 marauders.
Marauders have always attacked me on sight so far, no scanning, no moaning, they just bring it.
I am flying an engineered AX FGS, have not yet solo’d a cyclops(still not great at combat), and so far have dealt with 4-5 marauders pretty easily. Just remember to use silent running to burn off corrosive damage when necessary.
It really is good fun i must say!
