It would be great if people could track troop donations, either to be able to thank after the fact, but also to identify people that are donating the wrong troops when preparing for war.
I realize the question has been posed before, but from what I read it still has not yet been ruled out. I believe it is still a fair topic of discussion. I do believe it would be a valuable tool, not an encouragement to lower level players to donate. An interface like this would allow us to see everyone who is donating and what they donated. More than anything it would allow us to see who is not contributing their high level troops like they should be. For instance if you ever find yourself minutes before war starts, and you find some of your clans war cc's not full. You could see who in the war did not do their part to support the clan. In a team environment I think it only reasonable that everyone can be held accountable if they choose to be selfish and not be supporting their team!
