In my opinion there are Four Important places they should add to this game, as they are talked about alot but people can't really visit them.
The Source,
The Merovingian's Chateau
Club Hel
And The Merovingian's Blackwood Prison.
Now in my opinion in order to create these places, perhaps they should turn them into constructs, perhaps base them on the Datamine model in terms of size, since that place is big. As to what to put in these places well, I guess that is up to the devs and perhaps some input from the players would be nice.
Ok sure the Merovingian's Palace Keys are good, but they are just small constructs really and not the Actual Proper Chateau itself, would be nice.
Also it would be great if they could make Club Hel a proper place everyone could visit to instead of having to keep using the Pandora's Boxes to access the place.
Apart from that, that should do it. Unless anyone has anything that should be added to these places?
