You don't need the same fast-paced clicking that you find in a pure RTS, and the AI does a reasonably good job at deciding what to do. There is, however, plenty to do in combat. Positioning your capital ships and taking manual control of their abilites is usually a must. Next comes focus-firing, staying away from enemy tactical structures (or close to your own), positioning and using the abilites of your smaller ships and so on. If you only have a couple of small frigates, I guess there isn't all that much you can do (except focus-firing), but in large battles when you get higher up on the tech-tree there are a lot more options.
