Just a comment: We have tried bringing tides, havana, chateau, and russka back before – and they all kill the server – as in everyone just leaves. The maps are good, but only a few people truly like to play them.
Trying new maps is great. The Paris one looks fun, and I hope to see the fort one as well soon.
The only problem with new maps is that people suck and run away from them, without even giving them a chance. We will see, but I think they need to be tried out when the server is full, and hopefully people will stick around. Maybe give them an announcement (with vote) saying that we will be going to a new map for the server or something.
