Tie the Killer ranking system to the Killer and not to the Account

As the title says. Each killer should have its own ranking system cuz its usual everyone mains a Killer among all who is the one we use to progress our rank to become the best killer. And when we want just to practice, or even try out another killer we barely or never played we still keep being thrown into games aganist players of your current killer ranking ending up with awful results including you losing rank.

Also because on the contrary to survivors who are the exact same (gameplay wise) and only differ due to the perks you gear them up with; Each killer is a completely different gameplay due to their powers and unique qualities which makes them easier or harder to domain. Hencefort it would be great if every killer could come up with its own ranking system.

Cuz theres a huge difference between someone who achieved Rank 1 being a Trapper/Hag main to someone who reached rank 1 maining Spirit/Nurse. (Just to make an example lol)
