I think Supercell should make a war feature where we can send people into war.
So for example:
We can choose how many people we want in a war and who those people are, so for instance, in a full 50 player clan, we can send in 10 players for a 10 vs. 10 war.
This would be a great feature as this way, you could have casual friends/farmers still in your clan and not have to worry about them pulling you down in wars because they are not as active or skilled in attacking.
