I would like to say that I really really enjoy the concept of the one-way portals we have now, and this thread will not be about what is lost from removing the old city chambers (another topic). However if this system is going to succeed in what it's supposed to do, then we're going to need to criticize what we have now and how it operates, considering we didn't get to put it to the test before launch.
I didn't find the right solution from the Internet.
