Luffy is slowly building his reasons to beat Doflamingo to the ground and Doflamingo continues to be busy in Dressrosa.

I was expecting Luffy to hunt him in another island and it still can happen. He has reasons to travel till Zo to free Caesar. Although, I feel that the factory gonna be in trouble before Doffy get rid of Law. This seems to me as a priority and as a good reason for him to stay in Dressrosa and compete against Luffy now.

It is just a feeling, so don't expect deeper reasoning than this^^
