Yeah, I know all of that. I hate alignment, and I especially hate the redundant planes in the Great Wheel (why the hell is Pandemonium necessary? Just make it one of the levels of the Abyss. Or Hades? Why is Carceri evil? It's just a planar prison. It probably shouldn't even be a full plane of existence, just a large demiplane. Why do there need to be two different planes of war?
War is war! Why does basically every plane have 5+ layers for no good reason? This cosmology is overly convoluted and makes no sense!!!)
About half of the planes of existence in the Great Wheel are unnecessary. If you want to base a cosmology off of alignment, fine. Make there be a Lawful Evil Plane, a Chaotic Good Plane, and a True Neutral Plane and whatnot. But you don't need a plane of existence for every in-between alignment (Lawful-Neutral-Evil, Chaotic-Neutral-Good, Lawful-Good-Neutral, etc).
