Ah, that's rather what I expected - though it is slightly dissapointing. I was kindof hoping that some terrain might serve, in battle, to extend fog of war. Essentially blocking line of sight.
But as you said, it's a standard in most RTS games - so not an unexpected response. I really hope that, eventually, terrain will play a dynamic part in the battles themselves. One of my favorite strategy serieses, Total War, made things much more interesting because of the few ways that you could utilize the terrain to obtain very solid advantages.
