tbh, scouts are more specialized if they are unarmed. I like how they extend units range enough to grant them anticipation when a scout is in a group of combat units, encourages variety and tactic. I never did like their weapons.
Well i thought it'd be fun to actually try... Scout spam won't work against good players obviously, and you certainly need more than 350 to kill someone... I think altogether i sent 10-15,000 scouts at black in like 10 waves. Oh, and scout spam seems pretty good at buffering for your gunships against those t2 missile ships
