I think Bloc is a good thing to begin with, it's not gonna be about building huge bases with mingy little headglitches that require little or no skill to defend. Its gonna be about who is the better shot, who is concentrating more, and which team are communicating more. An aspect that zarp has been missing for a while.
However, I do agree that we need an additional district, so Im gonna suggest this:
- Military Base (Spoiler contains picture from h1z1 military base)
I think this would be a good addition, something similar to incorporate the 'big bases' that people want, of course, this is quite open, so this is just for inspiration, you could perhaps add some big buildings or big walling surrounding the place.
