i played a game against my friend. i set all my units in half life(HP) mode. then i chose undeath VS human. i follow the 三秒杀路线。all my three heros can withstand great punishment coz i bought 8 or 9 life potions. however, my friend managed to destroy my normal force in an incredibly fast way. after my army gone i could revive lots of skeletons but it worked poorly. i destroyed his minor settlement couple of times but i cound not kill his elite force(main force with heros as support). i have a slightly better skill than him but in this 50% life mode how on earth can i defeat him. help me la.
