Hijacking would be cool to have. I have no problem with it. I think the easiest way to deal with the vehicles is just when you get to the Moon Map changed your Heavy Weapon to a Rocket Launcher. I always keep one type of every weapon on me just in case i need to switch. You also need the Heavy Ammo now its not hard to get just Keep A, an C points then stay in the middle of them an defend them. An thats where the Heavy Ammo spawns at A, an C once it spawns take one then wait see if anyone gets the other then take that one if they don't. Then you have a easy way to deal with the vehicles. hijacking still would be fun.
