Object rearrangement.

It's not that important: in any case, rebuilding a town is cheaper than building it from scratch.

Are non-rebuildable, useless (and in the case of a town portal, downright harmful) towns from previous versions, reduced to the level of gold mines, better?
Or is the multiplayer cheat, where one of the opponents has a town of the desired faction nearby, while the other doesn't, also better?

Overall, I think there are more advantages.
