based on your numbers i dont believe you, raid loot does have blp. Link your char cause i want to see the number of kills you had on bosses last tier to make this claim. I've raided for a long time and do sales runs. I've never had some one in one of my runs go more then 10 bosses(unsaved to) in a row without loot. Not once has an unsaved funnel not traded something to a buyer... etc. You could be very unlucky and consistently get the same loot over and over again but across a tier you should see an AVERAGE of about 1 piece per 5 boss kills.
