What lute said was right on the money in my opinion.
"NOE hoard weenies would attack a field that had the greatest chance of NOT being seen.
(combat scares them)
They would pick a base furthest away from any enemy dar bar as they could find in hopes that nobody would see the base flash.
It isn't that the country being attacked couldn't put up a defense. If someone happened to be looking at that particular remote sector of the map, upped to check on it, and found the dweebs inbound then that NOE mission was doomed."
If you can only do it one way, its time you went back to school. There are many many ways to succeed.
Taking varying amounts of skill, teamwork, and timing.
The NOE attack was just the simplest of all of them to learn.
HT has spoken, this is the way it is. Make the best of it.
