True, not everything pops up in the little warning box, but that wasn't really my point. In a typical RTS, you have this: Your base(s), your enemies base(s), and a lot of dead space in between. There is no penalty for patrolling deadspace, beyond the certainty that your patrolling units will probably die if they catch sight of an invasion force; that's why you use cheap units to patrol, or better yet, cloaking units if the game has them. We already have that: scouts. Even if it takes a bit of a push, you can usually get a scout +1 beyond your border line. It doesn't need to move around, it just sits there monitoring status and any abnormal accumulation will be obvious in the galaxy chart. Beyond that, we have perfect vision within our borders. Each planet is guarded not only by full sight, but in many cases the ability to detect when and where. Not always, but at the worst we at least know something is happening.
So: given that information: what is the point of moving ships around *within* borders? They are not adding any additional recon information, and their movement could very well mean they are further out of position than they could have been had they not been moving around, when an Enclave shows up.
I don't know. It just seems to me that if you are playing a setup that encourages surprise attacks, it would do much more to tech better sight (cloaked scouts) and anything that will increase the mobility of your forces: Spacetime Manipulators; Logistics stations; Spire Telewarp Transports; etc. What good does slowly moving ships around in a circle do to improve the situation? Even if they *are* milling around in enemy space, what is the advantage of doing that over pushing a scout in and sitting quietly?
