Seems like you guys don't care about this game anymore. Just do something to keep the game moving forward. All that you have done in the last 6 months or so is release new cities with ok troops in them. Here are a few things you could do
Open the black market and let us trade items with in our alliance
Actually run some tournaments, give out GW cash as a reward. But run them in a % of power gain rather then overall power gain. Try to help out the smaller guys
How about a world on world war. Put all of Nelson against all of Wayne. Yes I know you'll have to get rid of the obvious cheating in some worlds.
Beef up the defense of the walls or make the build times quicker. If I send in 5000 stealth I'll wipe out an entire level 9 wall easy. And it takes about a month to build up a level 9 wall.
Diamonds?? Where are they?
And the other SR, I forget what it is, but just keep things moving forward in the game
