New addition idea: Ability to build an 2nd army specifically for clan wars. If giant/healer army is already built in regular army camp then we could use that army in war or build a hog army. In other words being able to build 2 armies and decide which one to attack with in war or regular attacking (ie GoWiWi or hog). Both armies would take from your standard resources.
Also it would be great to have 2 spell sets to choose from depending on what army you are using.
