Hitech wrote that 6 yrs ago. Only he can tell us if he still feels the same way now.
With all the changes in the game and numbers not what they were back then maybe it would be time to experiment and see how 2 hours does. As stated it has nothing to do with spies giving away CV locations, etc.
The map that is up at this very moment Rooks have not been able to win for 24 hours, one base away numerous times only to lose the %min required...
I was going to switch to Rook to help them win the map but I knew it would be 6 hours later before I could go back and at night I like being with my Knight buds....
