If anything they should work more on the S+CBMM mix. Tighten the CB boundaries a little so the so the minority brackets don't play folks across the globe so often by default. Loosen the SB boundaries a little so queue times aren't as bad on the minority brackets but would still maintain relatively balanced SB lobbies for all brackets to prevent stomping. We aren't necessarily too far from an option that'd minimize frustration across the board.
