Conquer style war

There needs to be more war modes. For example how about a war style mode where each person gets a base as usual but there are 2 extra bases for each person. Each base you attack and conquer you keep but must send troops on the base to keep it. If another base goes after the base you conquered they must get a full 3 stars to take it away. You keep playing until all bases are conquered including the enemies. If your base is destroyed you cannot attack.

I'm getting the concept, but needs more clarification.

Sounds like the board game Risk...

That basically means if somebody can beat one of your bases then they can beat all of them.

I just now realized the unbalanced part of it. Maybe only certain levels can attack certain levels.
