Learn the difference between burning slow and spreading fast .....
Facts...
1. Amaterasu seemingly doesn't cause great deal of quick damage ..... Raikage's hand didnt burn down in matter of seconds Nor was the Samurai burned quick enough.
2. Amaterasu spreading is kind of limited by the user .... note how quick spread of Amaterasu was always marked by the user focusing on the target (Sasuke ignored the Samurai and the Raikage put his hand in the amasusano and ***** slapped Sasuke after which Sasuke was not seen focusing on) ... Only contradiction to this is durring Itachi's death which can be explained by fact that with demise of the user the tech went rampant and there was seemingly enough time for the flames to spread in the forest.
