Listen, all of you from older servers. Your old school method does not work on newer servers (namely 60+). Or at least say which server have u had success. Not all servers are created equal.

If you think that hitting a valley hundreds of times just to get a few medals are hard, why dont you open an account on the new server? You will cry (either way, farming or when you finally get one -rose) hunting for medals.
There are 0 medals, ZERO medals in valleys except lv 8-10 and medal types appear in random.
