What if tanks could drive through and shoot through bushes? The new terrain update is going to bring us more trees, more bushes, and more buildings. Having all of those stopping your tank dead in its tracks will most likely severely limit where you drive your tank. Bushes should just block line of sight but allow the gvers to still drive through them and shoot through them. Trees, buildings, and hills can provide hard cover from enemy tank rounds.
I'm sure this is something HTC is looking into for the next big update.
