Blowing up a god and trying to wipe out an army 100,000 to force out his arch-nemesis isn't "wasting the power", especially on "fodder" as you put it. I don't know how many times I can say that the bandages are for straight up mystique until people get it. They served no actual purpose other than to conceal the tattoo. Natsu has used Igneel's power 2-3 times prior to the actual fight. He only released it all at once just now. You can keep believing what you want, but if you parallel Igneel's roar with the Roar of the Fire Dragon King, they are the same. It's a small amount of Igneel's magic left to fuel and extremely powerful attack. Natsu is not capable of that all by himself. We saw that when he used a regular Fire Dragon's Roar against Bluenote. Compare the two; the difference between Igneel's magic and Natsu's own is simply staggering.
