If you have donated a lot of troops, (1500+) your clan leader and co-leaders can make you a "donor". When you hit 2000 donations, it is an automatic rank achieve. It would have some perks regarding troops, like declining others troop donations if you don't like them, such as if you ask for dragons but someone gives you bad troops for what you're using the dragon for, such as goblins or wall breakers. Or maybe a multiplier to your exp earned for donating! Please feel free to put more perks in the comments!
