I say no thank you. Because the vehicles make it seem like it's just a remake of halo. And like many other people have said, it's stupid and not at all fun if you can't get into a vehicle. For instance if someone gets on a tank, all they have to do is just sit in it and they can basically kill anyone that comes near them. Yes you can kill someone using them but it's very hard. So combined arms is fun, but I would not want it to be a permanent game mode.
