It is common for coalitions to help their menbers by sending defense to their city if they are being farmed by a player with a bigger army. Usually done during PVP. Many players send defense to you to trap the bigger enemy, Great strategy for gaining points.
If your coalition will not do that for you then you are probably in the wrong coalition. Teamwork is the only way you can stand up to heavy coiners.

Where can we find terms and conditions of the game ?
About whether the game's people or game-connected people can play against us and thus have the superior advantage ?
Thanks
