Point of clarification: 3+ stacks are not a "separate pool". We only ensure that if there is a 3+ stack on one team, there is a 3+ stack on the other team. This prevents the scenario where there is a 3+ stack on one team, and all solo or duo queues on the other team. It does *not* prevent, (probably worst-case example) a solo queue player filling out the single open slot in a 4-stack vs a 5-stack.
