You need to go back and reread the chapter bruh because you will clearly see that natsu didn't unleash igneels power until he took his bandages off and you can tell by the aura that surrounded him when he unleashed it and the fact that zeref acknowledged the power and the heat that came from him when he unleashed it. Like natsu said when he uses igneels power it can't come back so what sense would it make for him to waste some of that power on fodder.
