If you believe these big hits aren't being paid by other professions you are wrong (doesn't matter what MA said, it is obvious to anyone who plays enough to know). If you think the losses some people incur on that BP goes back into the loot pool, you are also wrong. This BP works differently, it takes more, the part it takes disappears, and it is paying out with loot from mining and hunting.
Last year migration...(no EP BP's) tons cycled on migration, and many huge hits...this year, tons cycled, only one big hit, and lots of EP IV Ath's during migration. Coincidence? Sure, you can call it that...but smart people know what's up...
