I agree, I have been farming medals every day for about two weeks and not lost a single life in that span but have aquired 10+ roses, 8 lions, 5 honors and numerous others, all from lvl 10 valleys that have 0 cavs and/or archers. I just space my attacks a min of 10-15 mins and hit the same valleys over and over. Grass and hills have been the best producers for me with grass ahead by a large bit. And i am on server 114.
