Can you please explain how to use this formation? I cannot see the advantage of having un-stoned units in a very defensive position. It would be hard to go on the offensive, and on the defense you do not have much armor or HP. I mean, in good hands you may be able to make good use of the units, but I see no positional advantage (except for blocking LOS).

It Rockzors! Thats how. I recomend playing me with it on legends and seeing how it is played.

i dont see it's effectiveness. if you can force the person on the offensive, it will break apart. the obvious mistake would be to rush in, with a wisp, frost, berserker waiting for you. but id say a planned attack that will draw out vulnerable units will result in an easy lose for you, regardless of your high skill.

It's AU. What high skill?
