I’ve mained Cammy since the game came out (I’m Silver in ranking), and I find myself wanting to try other characters. So I pick Birdie and load up a Casual Match. Instantly get matched up against a Super Gold Cammy (which in my experience should go in Birdie’s favour). I then get absolutely destroyed to the point where I just put my stick down and left the room half way through the second round. Didn’t learn a thing. I then got matched against a Gold Bison and the same thing happened.
So just now I am actively discouraged from ever trying a new character again. Unless I pick a new character and just keep losing until I am back in Rookie, but where is the fun in that? I know Rank doesn’t really “matter” but it’s nice to have the feeling of Progression.
Anyway they should keep your rank for each character.
