Some discussion hapenning, thankyou.
Yes, to allow a base to survive when being attacked, you could simply chose to keep humans off the base. The enemy would have to run base assault after base assault to run the hex down, no different to having non-destroyable bases. To prevent the enemy from taking the base, a human opponent could allow themselves to be drafted, and perhaps even self destruct the base. While that has been levelled as a criticism, its not actually all that unrealistic. If no human opponent is present, as Corbomite stated, the base would captured when the hex flipped.
The question then, is this preferable to having bases destroyed by deep strikers on an empty server (as has hapenned in the past) or having persistant permanent bases that are immortal (which solves the previous problem but is unrealistic).
What about other options? What would be the ideal solution?
