So, I haven't bought the game (yet), but I'd like to chime in on the concept of zoomed out strategic type view. (long time SC: FA player)
Strategic view is to oversee the entire area where _multiple_ battles may be taking place. Basically...get an overview of the whole war. Which is a feature of this game. In wars, you need a quick way to get a basic overview and concept of what is going on in each battle, and ideally (for video games) be able to quickly zoom into that area to direct your units. I understand the Dev's don't want to simply copy SupCom, and want to show the power and beauty of the game engine by always rendering the full unit, but the further you zoom out, the less relevant that becomes.
Using icons has a long history in battle/war management, all the way back from sand tables and paper maps and up to grease pencils on a board. For example, modern day CAOC (combined air operations center), here's an UNCLASS view of the big wall screens, which can give an good overview of the area of responsibility. See all those symbols?

Granted, we have the luxury of full knowledge of visible units, how to render them, etc, etc, but at a very large scale icons work because they let us take in a lot of information at a quick glance and tells us the most important bits that we need to know. Once you get below this level...yea, I don't mind the Dev's doing their thing, because it's their game. Although it's great that they take and incorporate feedback from us, they still have their vision of how it should work.
Also...as with some of the others, I have no clue what "click to zoom" means. The way it was used it sounded like click to zoom out which doesn't make any sense to me. If you're talking about click from strategic view to zoom into an area/battle on the map, that does make sense.
EDIT: Here's a bunch of modern day military symbology. Doesn't need to be nearly this complicated, but basic differentiation between "artillery vs tank vs fighter vs bomber" is very useful http://axisandallies.wikia.com/wiki/Military_Symbols
