Hi. Well you're not gonna stop the lootgoblins for sure. My group came across a base built inside the warehouse at one of the citydocs. They had blocked one of the big doors with a huge military tent, and locked the other door with lockpick. Pretty clever.
But one serverjump and we had breached the base. Pretty sad.
I hope they add some spawn block system or similar. Because the is no incentive for me to spend much time on bases.
