I think this is going to be too fun actually. Now let me ask this. Will we be able to fight from the air? I mean if your changing ballista’s to being able to shoot us out of the sky then we should also be able to counter. Say for example, how about since Engineers use bombs can they drop them from the sky. Be too fun to have a squadron (squad) of engi’s fly over and bomb the crap out of an enemy tower or other encampment. Or better yet to soften up a large Zerg so a small group on the ground can go in and finish them off. Just some thoughts that came to mind as I read this. But it could be interesting and I think a lot of fun.
