Why does every idiot come with the argument: Oh every flagship has a sub and a rare or variant, Duh -_-

That does very well not mean that Zin should get a rare.

Let's look at the other sub and rares of the flagships:

Rathalos: Azure and Silver are just a recolor due to genetic mutation. They are still the same.

Rathian: Same for her.

Tigrex: Brute is just a variant as stated on the "Ecological Info" page and Molten has only the added effect of Blast with it's attacks. Nothing new with Blast.

Nargacuga: Green only a recolor with barely any changes and Lucent can partly go invisible and has poison. Still no heavy change in moveset.

Lagiacrus: Ivory is a land type and Abyssal an full-underwater type. They still use thunder all the ime.

Brachydios: Aggressive Variant

Gore Magala: Variant with Shagaru attacks

Zinogre: Complete change of element.

Stygian Zin already looks powerful for a sub and unique. A rare cannot possibly top that.
