I was wondering when someone was going to get around to suggesting this
Attached is one of my white papers I had repeatedly bombarded Aaron with during the beta (this one was sent back in September 2005). Anyway, what it had proposed is similar to what is being discussed in this thread. This actually formed the core of my "Ground Combat Mod" I mentioned a few times (but was rather secretive about) that I worked on/off throughout the beta. I have a score of modded files, primitive graphics, balancing spreadsheets, etc. on this if someone wants to take a serious stab at such a mod, but I honestly don't have the time anymore.
