So, we are 11/12 (10M) on normal mode, we have Cho'gal down and Al'akir down, still wiping o nef (having problems on p3).
We can pretty much start heroics on BoT because everyone already killed Cho'gal.
But how about BWD, I mean, we didn't killed Nef yet, BUT if I bring someone that killed Nef already, can we unlock the heroic modes for that place, or everyone have to had killed Nef to unlock the BWD heroic content? I know it worked on Wrath, but i'm not sure if we can still use this feature.
