Its balanced for a few reasons mate... Inside has a hard time sniping out due to the sun, but those outside sun dwellers need to go in for the flag. Its an even trade. Outside can push in from three areas that have rotating cover if they want. They just need to do so smartly. Its a laned map. Those lanes are fairly even (one side has height advantage, the other has sun. And the sun advantage can be minimalised by lowering your brightness settings).
