If I were in charge of Black Panther, he'd only get involved in world ending threats. If HydraCap had stuck to America and not wanted the cube fragments, Tchalla wouldn't have cared. He'd still help the Avengers, but if Wakanda security wasn't at risk in the future, he'd pass on any mission. I liked Secret Empire and for now this story better than AvX or Hickmans attack because the enemy was coming for something they already had. Tchalla wasn't indirectly responsible for causing the attack.
