Merge the Defense and Military Tech-Trees
I like the new defense techs, but the new tree is not needed. Let's face it, defense is the same as military. So just put them both under the military tree and be done with it. Besides, having 2 tech trees messes with my pavlov's dog mouse clicks. The ONLY benefit that I see from the 2 tech trees is that your can research both military and defense at the same time, but I am willing to give that up for a more understandable tech tree.
