The current radar scaling seems to be lacking, so I've come to propose an idea I've had in the back of my head for a while.
The "seismic radar," the way i would like for it to work is:
1. Track the movement of moving units only, no aerial or static buildings(literally means it only sees units moving on the ground)
2. Range of somewhere around 3000 Elmo
3. A mid range price, 150-250
I find the current disparity between radars to seem a bit strange, seeing as how the price ramps up so much for what is a 50% increase in range, kinda making it not feel like a natural step up but more of just a late game option when it doesn't require much to be used.
