Saltiness, anger, fury, rage. You've experienced all of these if you have been waiting for 8 hours for someone to fill your request of a max lava hound so you can attack in war, and someone finally donates you something—except that something is 6 hogs.
Misdonating is a very irritating thing in clans, especially if it's to your war clan castle. And the worst part is, it's very hard to track down and kick the misdonater because you're offline most of the time it happens. That being said, there's a very interesting feature in Clash Royale. If you request then go offline, when you come back online you will see who donated you how many Minion Hordes (for example). There's also the fact that you have to request for a specific card in CR.
Taking one or both of these features from Clash Royale and implementing it into CoC would be very helpful in finding those who misdonate and would also virtually eliminate the misdonaters entirely.
I seriously agree with this. I've been in my clan for 8 long months, and I'm co- Leader there. When I ask for a dragon, some *badwordz* give me 6 archers and I'm ready to kick someone!!! Please do this!
