That is where Natsu steps in helping through the magic of team work and cooperation, also I think Igneel, during his fight with Acnologia, will some how get his flame to Natsu and Natsu will be able to eat his flames, increasing Natsu's fire Magic ability. Oh yea and there might be a critical weakness to E.N.D like his book.
