The main difference is that NB scorch is significantly less lethal than what was shown in the anime. It can burn yes but it only slightly dehydrates the opponent, weakening them overall. Rather than turning them into a dried up mummy husk thing, so its not an instant kill which is fair enough i suppose. If you have no further questions we can move on, try to focus your wind and fire chakra to form some scorch.I don't know? The only that comes to mind is that different forms Scotch can take on NB as opposed to the canon usage which just takes the forms of suns as I said in my previous post. Also in canon Water> Scorch in terms of S/W but on NB it's the opposite.
