Someone explain to me how this in the slightest is "balanced"

Look at the most recent game (as of today, 12/15/2018) and review my game as Quinn going 2/11/6. You'll see a Neeko (of course) that's a Plat 4. You cannot convince me that there are significant and separate differences between ranking systems between "Ranked" and Draft/Blind pick. Ranked simply means those that are competitive about it are playing for a rank to compete. Unranked means it is still casual and not documented, but there must still be a basis for ranking you against other players. This isn't Call of Duty, or a Battleground in World of Warcraft where it's potluck with who you get paired up against. We know this.

I'm begging for an answer as to how in the world is this considered balanced?
