Yea that's what I do but not just hackers but any other person with missles. Also, if you have one person in front of the army, you can tell if the enemy is attacking by seeing if he gets attacked, you know some enemy units are coming.
U know I should really be putting this on a different thread, but it seems like with the hospital upgrade and the infuence dudes came up there's a new strategy no one knows about. Ex. My bro and I were multiplayering and we had a 76 winning streak. Then, some dude came up & beat us with groditz and mod. phantoms. Also, my bros black queen couldn't hit the dudes army at all and they were all groditz. WTF. Can u find out that strategy????????????????????
