Okay - so having watched that video, I think Plarium has done a decent job of planning this new city out. However, I'd implore them to not just leave it by the wayside as they did with Doom Tower, IE, having static rotations. The mechanics of each of the districts, with the specific limitations around the types of champs you can bring - make that stuff randomized each rotation. Then you'll actually have fresh challenges, and not simply a "set the same team you used last time and hit auto".
