Your mod doesn't make any more sense because you make it teired.
I disagree. RotaryCraft is a perfect example of how tiers in a mod make it make more sense the farther you go. If someone can't grasp the concept of a simple gasoline engine, then there's no way they will understand how to run something like the extractor, which has varying minimum requirements for each stage.
