OK, so tested this thoroughly… on all official servers the purge strength is set to 6… when its set to 6 you don’t get the lower end attacks… the ones that have say the THRALLS that you want…
this needs to be Random if set to 6… that should be 1-6 meaning there is a possibility to get hit with MEGA creeps but you still might get hit with light purges form time to time… who the hell coded this… makes no sense at all to not be able to get these on official servers…
