Remove camping spawn buildings from meta game

[Aaron]

There should just be a set of defensible stages before the attackers reach the spawn tubes. If the attackers do get to the spawn tubes, they should be able to destroy them and end the fight. Also, the spawning room should not be accessible to vehicles (preferably underground).

You wouldn't even need spawn shields with this setup. The spawn defense stages should be fairly spacious and quite defensible. The players that use the base's defenses should be the "shield" instead, and if they fail then the war ends without any spawn camping. You would get more of a situation were attackers and defenders are pushing against each other, instead of defenders getting instagibed out of the spawn doorway.

However, what if the attackers simply destroy the spawn tubes before anyone notices? If you don't want that to happen, then maybe the spawn room should only be opened to attackers once they get further down the base hack progress (25%? 50%? 75%?).
