People block more effectively with the tank than a bus because of the gun. So if you're complaining about blockers, one way to deal with that is nerf the tank. And when I talk about vehicles with weapons, I don't mean the ones that shoot at people as they race. That I'm fine with, it's part of the game. I'm talking about ones that get a weapon early on and cut across the map to the finish line to disrupt the finish. Tell me how that's fun for the rest of us.
