I mean you do enjoy the action, you just don't do it from a zoomed-in perspective.
Watching videos online doesn't give you the full effect because you don't even know what units you're using. We're talking about a game here which has a unit selection of nearly a thousand tanks, infantry, helicopters, aircraft, and more, from 12 different nations. Building your own deck allows you to connect with the types of units you've grown up admiring your whole life.
As I said before, in an hour or so I'm going to post a new thread about another game which is similar (in terms of representing modern combat), but which is much more zoomed-in so you can "enjoy" the battlefield experience a lot more. The consequence being, of course, that you lose the large-scale battlefield perspective.
