In the current build of the game I strongly advise against making a roadblock PMBs, because players will simply go around you or over you, defending players will defend the static base behind your roadblock, and the tankers will be the kids who kick over your sandcastle. The problem is that there is no reason for anyone other than the couple players personally invested in a roadblock PMB to bother to defend it. I suggest solving this by adding dead control points to the play area between many of the existing bases. It would be easiest to find locations for these on Indar, which used to have many more bases, and still even has active garages around the place with no associated spawn points. If not built on, the dead points aren't part of the lattice system, players can drive on past them as they currently do. If a silo is built within 100m (the existing power range of a silo) of the dead control point, it activates. It then becomes part of the lattice system. Enemies cannot pass by and capture the base behind you without dealing with you. I would have two ways to deal with these: Option 1: Capture the base the old fashioned way, by beating the capture timer. Once the capture timer completes for the attackers, the base detonates (much like currently happens on the flat top of Ikanam bio lab) and the control point shuts down, removing it from the lattice. The attackers are free to carry on. Option 2: Destroy the silo. Doing so removes the base from the lattice and attackers are free to carry on. They can stick around to fully kick over every tower in the sand castle if they want to, but there is no requirement. To activate these, full connection to the base should be required, so building them behind enemy lines wouldn't achieve anything. If you start building while back capped, you have to re secure the back cap for your base to activate the control point. I also wouldn't have the silo activate them until it is fully deployed. This way, even if the builders immediately replace their dead silo, the attacker still get about a minute to start the capture on the next base. I'm trying to think of suggestions that would add variety to the game, and keep things balanced. I'm trying not to be one of those players who only plays scissors and wants bigger scissors. If you've read very many of my posts you know I play construction, but I think this addition to construction wouldn't be anything unfair to anyone else.
