I'm on server: 83
I've tried every medal farming guide out there with little success. Frustrated, I had given up and focused my attention on attacking lvl 10 valleys with warriors and some other misc. troops for prestige. That's when I noticed something. I was bagging alot of medals (rose and lion).
........Do you feel that the valleys' hero lvl has something to do with your chances of getting a medal? I've found that probably 90% of my attacks resulting in a medal have been against a lvl 10 valley that has a low lvl hero ( under 12).
Thanks for doing so much work on this topic. I'm going to follow your suggestions and see if my odds improve.
