yapyap the destroyers Hgrunts cant take out marines nor grunt squads and dont fire fast enough and unlike marines and grunts you have to get a raid camp then wait for it to finish then build them but they have a slow rate of fire (dps) and to beat the units the opponent starts with requires a methane wagon to give them any strength and i think they could do with a shield upgrade or needler upgrade for dps, at least give them something
