its a bit confusing, but I asume you have BBoY (flex), Toxic Totem (LFR) and PBoI (Flex)? ... than go Black Blood/Bindings ... only change them for there nhc versions. general rule is
Bindings>Black Blood>Totem. iLvl+>iLvl-... with the Exeption of the bindings, even their LFR version is supreme (not the buff, but the passiv)
