Its not the scouting that bothers alot of players. I think its more of orbital play where you have to hunt down commander that have fled the planet. But good point on the radars..
I agree here; it's incredibly difficult to scout a fortified moon, for instance. Right now if I want to scout a fortified base I send several astraeus to it since they're cheap, their vision radius is pretty good, they're 5 times faster than an orbital radar / advanced orbital radar and they can evade orbital units and umbrellas by passing through the orbital layer. Not to mention I have a chance of landing a fabricator with it.
