Anyone else use the sneaking symbol?

The sneaking symbol is vital. It is the only tool we have to deal with the fog. In many situations you can pinpoint exactly where your opponent is based on the current situation. I'm not sure if it's intentional or just the game lagging, but the time the symbol spins seems to vary. I wonder if it spins longer for a higher cost unit? If that's the case, is has even greater value.
