why are high tier little legends purchasable?

i don't understand why little legends are not implemented in an feed/care/evolution kind of way. why create different tiers of the same LL if you don't "manually" evolve them and can just buy them.

its like buying mastery 7 champions from the get go.

personally i think they should work like summoner names. where you are locked to one and have to pay a ton to change it. like a semi real pet. so you're more invested in your specific one.

the monetization comes from skins that would then change the, say, furyhorn into different versions of furyhorn, more than just chromas though (like champ skins, maybe even release "legendary LL skins"). so more like species where a furryhorn A can have a different personality from furyhorn B(different animations due to skins instead of chromas(. maybe even monetize "outfits" and "accessories" for each. the chromas/breeds can be permanent "dyes".
