Just thought I'd kick this ball and let it roll down the hill but Alliances are a huge part of the game, it would be nice to see it explored.
A few, myself included have NAP's or agreements inplace, it would be nice to see a settings option so we could enter these on to a list within the alliance, this would then stop members having the option to attack these players and vice versa 
Any other thoughts/suggestions of what you would like to see?
