Give Squad rarity some purpose

I was thinking why don't give squad rarity some use? Sometimes I see ultra rare Squad sold on really slow price, like they were common ones. It would be nice to see some ranking list of the Squad based on rarity, and for example, the more rare the Squad is, the more cake in the IFO you can commit. We could maybe implement some pool/farm bonus to the Squad owner which gives the bonus based on rarity.

I don't know, these are some utilities that came to my mind, but actually anything else would be super. What do you think?
