Ugh these medal guides are frustrating. People post conflicting advice and don't mention which server they are playing on.

I'm playing on server 79. Tried all the strategies here;
Attacked one valley over and over with scouts, attacked one valley over with minimum archers, abandoned, not abandoned, attacked different valleys each day etc etc.

Must have attacked well over 200 times and so far no medals, zero, zip.

I've either been monumentally unlucky or it's simply not worth spam attacking for medals on sever 79.
