I know they WANT you to destroy the walls, but get this.. the demolishers are made to smash the walls down with rams right? well guess what? When you try to drive up close enough to use the ram, you go right through. YES it can "technically" be defined as an exploit. But its not the type that you have to do some special thing to make it work. Its a bug that lets people, knowingly or not, drive through the wall when they "try" and ram it down. So if they didn't want it being used, they would have fixed it or disabled demolishers LONG AGO! You name me one person who has been banned for driving through the wall. I can tell you I have been reported driving all 5 of my demos through and killing the orb wall and winning for us. More than once. They are obviously allowing it until they find a way to fix it. ( i reported the bug myself the first time it happend to me, weeks ago )
