"On that day mankind received a grim reminder: we lived in fear of the Terrans and were disgraced to live in these cages we called walls."
It's not about helping the defenders, it's about making sure vehicles don't get in and **** yo' ***. Btw. The Octogon or what has defendable walls.
They help defenders no matter what because they stop tanks from running up to the spawn and blasting it or camping the point. The walls are fine they way they are. Honestly it would suck if you could shoot through the walls, it would be near impossible to get inside the base. They set it up so vehicles can't camp inside the base and spawn camp. That's good enough for me. Even if you're on the losing end of a Zerg you can still have fun now and get some kills rather than sit in the spawn and either get killed by your teammate or walk out and get shot by a tank.
