I wonder after doing the Sentinal and there are three bosses each dropping small gold orbs it occurred to me that maybe the reason everyone is getting low scores on this map and saboteur is because there isnt any sub bosses to drop those orbs, which seems to be the only way to boost the score for higher medals
Not entirely true, elite enemies also drop orbs; Bosses just drops a larger shower of them.
Really? What classes as elite? Cause i know they came from large chests thats cool if they do 
but original point still stands
The extra heavy units like bonecrushers and enforcers, if I recall correctly.
