Priorities . micro it back first . If you have time , remove it from your army , if you have time send on wood . So if there is other things about to die , just micro the ghul back first via minimap , then when you have do the other stuff . you can still send it to harvest lumber later . one thing people do is send your whole army back via minimap , then just deselect the weak units and fight with the rest again while putting them on the ctrl group again . this is quite suited if you are not too fast , fast players do not do this anymore , but it is quite handy when you are not too quick yet . little enhanced retreat the weakattacked unit a little then do the whole army back , so it doesn ' t get blocked . This all requires speed still .
