I def think that Tchalla should have some beef with the Avengers. He make it perfectly clear that Wakanda could not be implicated in the actions and then they still brought the fight to his door. Wanda is to blame as well IMO. She teleported the Avengers back to Wakanda (instead of Kun Lun they would of been safer for the time being.) which lead to Namors attack.I just hope Tony's involvement is mentioned too. He shouldn't be completely blameless in this, either.
