Here's InnoGames doing something on the topic.
The most discussed topic has never been 'neighborhoods are dead because of watchfires/defense GBs'. The most discussed topics have been the opposite - players unable to defend themselves because of a big difference in the ages between the players there.
So discuss how it affects you - did you notice any difference, what type of difference, is your neighborhood now more balanced than before. Maybe wait for a merge to actually take place and there will surely be something to discuss.
darkstar do you play in your main country? the top neighborhood? where the best players are? the neighborhood is active or dead?
and when I say that the neighborhoods are dead I speak of the battles that used to be made and it is now impossible
I'm on my main world over 2 years now in the same neighborhood, i started small and now I'm the number one player in the same neighborhood, what I see is that only change the last 5 or 6 players and are the weaker players.
So I speak from experience, the neighborhoods are dead because the plagues of the whachfires and counterattacks of defensive ge's
To clarify and finish, I speak from the perspective of where I play mostly.
