Why Isn't omniverse Ben10k appreciated more?

I personally think the biomatrix is the coolest concept ever, yet a lot of people, especially the Ink Tank guy thinks it's a mediocre feature.

I agree that the design is awful and lackluster but who cares when you can fuse aliens. Fourmungusour was and still is the coolest transformation I've ever seen.

I would love to fuse big chill with spitter. Imagine being frozen in solid acid.
