Regarding August, he can be true to his reputation and still be weak. His reputation is for knowing a shitload of different magics, but it says nothing about his strength after all.

Not that I think for a moment he actually is weak, I'm just speaking hypothetically here.

Just look at Gildarts. He has (shown) only one kind of magic and was still the absolutley strongest mage of the series pre-timeskip, save for Hades perhaps.
