How many more bonuses can we stack on our heroes? Because right now it seems that we are going to get drowned in angry nids if we don't try pushing them back somehow. Maybe we can try pushing out with our main army, drawing out their synsapse creatures and smashing them with a goon squad of hereos. Might be dangerous, but that's the only way to get traits. Perhaps with a full attack from the void too, we can stretch out their concentration, and win one of the engagements.
