Ah I see. You can control individual units in the sense the they may not be part of an army yet but I’m hard pressed to think of an advantage in doing so. It’s really not that kind of game. You’re not going to be manually firing off a unit’s abilities or dodging a projectile, the game just doesn’t operate on that scale, in my experience.
If that’s your primary concern I wouldn’t write the game off as I think you may have the wrong impression. I intensely dislike micro and the lack of it is one of the game’s better points, IMO.
