So what your saying is you want a worse version of Epochs building and would rather have shacks at endgame? In epoch you could make a locked garage, helipad, locked doors and have fun in the process. (especially if you manage to get a chainsaw) I play with a few friends and making a well sized base was one of the best things to do other than the PvP and AI missions. It gave you something fun to do when you want downtime from combat.
