You just have to watch them close. If my #2 guy is hitting, I know #3,4,5 are hitting also. since they are on follow on the "leader". I have found with melee, its good to be on the front "side" of them. On really large mobs, if you are in the middle of them or under them, you start getting "You are not facing in the right direction" or whatever that annoying msg is. The only time I will fight head on is if I know there are no knockbacks or AOE attacks incoming.

In those cases, I just stack all my guys on top of each other and go to town. I would really love to tell you there is a science to the whole thing, but I have just gotten to the point where I know whats going on in a half a second and fix the problem on the fly. I play with all my guys on one monitor, 1 pc. These guys that are playing with 3 or more different monitors I just don't get. I have a smaller "view", yes. But I see everything and can react much quicker if all my views are very close to each other.

When I am running through a zone, I will usually have one guy facing backwards as a "rear view mirror" of sorts, one looking to the left and one to the right. The other is looking up a little. I cannot tell you how many times I have quickly moved and pulled someone out of the sky to kill them in about 2 seconds. I know they are like "WTF just happened". 5 boxing with your views closely together like this prevents you from being "surprised".
