I tried to get a video of me and my friend trying to do this but it didn't work out. During Build Time, players with the any class are able to bug into the enemies turf. The system that pushes the player back when they're on the opponents turf while in build mode doesn't work out. I've seen many players abusing this system and it gives them the advantage because they basically corner the team immediately. There may be multiple solutions to fix this but it could end up bugging the game. Either way, this should be something that needs to be changed.
