I have been farming strath as ret for a couple of weeks now. I'm not in 'amazing gear' t5 mainly with a little t6, with a crappy weapon and legs.
I can do a baron run if I don't get impatient in 19 minutes. I do this once a day, and once or twice a week I full clear strath for the runecloth. People on my server are gaga over getting the ambassador title so I can sell stacks of runecloth for 11-17g a stack depending on the day, and a full clear of strath will net me around 20 stacks. PLUS BoP junk to sell, and BoE blues + epics for shard/AH-ing.
I have had the skullflame shield drop 3 times on full clear runs. That is essentially 500g in my pocket everytime it happens, and I don't even have to list it on the AH> People love that shield.
