The old B/P worked just fine and pwned SF and Tombs, unfortunately, ANET nerfed the necro's even more by saying pets no longer leave corpses. This basically killed the b/p run's...

B/P isn't nerfed; the pet corpse update doesn't matter, unless the group is bad.
edit: Unfortunately, player perception of that update may differ from reality.
B/P is dead because pets dont leave corpses. The idea behind the pets is that they'll keep getting resed, killed, and making a nonstop supply of minions in addition to the corpses of the enemies.
