Hi All,
This came up recently:
2 protoss scouts attacked an area containing 2 mutalisks and 1 scourge. The attacker arranged two skirmishes against the two mutalisks, leaving the scourge out. As the scourge is not a FLU nor an assist unit, what does it do? The way we ended up playing it was having the scourge just sit and do nothing, the two mutalisks were destroyed and the scouts were then forced to retreat. Was this correct? Thanks.
