I know when Mecha Jaraxxas came out, there was this glitch where odd Warlock wouldn't work if Baku was in your hand. But that's not the case here. There doesn't seem to be any rhyme or reason for it not to activate this time. Although both times it's happened to me, it was against other Demon Hunters, who weren't Odd demon hunters. (which personally is the only reason I see to play wild Demon hunter.) Any theories?
