Army "reserves" for clans
So we have plenty of people willing to donate troops in my clan. However, starting out as a small clan, not many people are online at the same time (many people have jobs, school, etc). Troop requests can take hours to be filled sometimes.
It would be great if the clan could have army "reserves". Housing for maybe 50 or 100 troops that anyone in the clan could donate to. Then when you need troops you can go take the ones donated to the reserves instead of waiting hours for someone to donate to you. Restrictions could be made if needed, like you can only donate/take 5 troops to the reserves every 20 mins or so.
Would also help a lot when a clan is at war. Someone asks me for an expense power troop (ie lvl 5 golem). I make one, donate it to him. But since it takes so long to make, he had to go offline for a bit. He gets attacked and the golem is used for his defense and is no longer available for him to use in the war. With the "reserves", I could donate it and he can take it out himself right when he needs it.
There are plenty more examples of times when a feature like this would come in handy.
