The champion pool question is the second-most-asked question in solo queue, behind “which role should I play to carry.” The answer is rank-dependent and the boost-team math is clean: one-trick if you’re below Gold, three champions through Emerald and Diamond, expand to four or five at Master+ for ban-phase flex and counter-pick value. Past five active champions in a single role, individual win rate slips enough that the wider pool stops paying for itself.<\/p>\n
This breaks down the three viable pool sizes – one-trick, three-champ, and wide-pool – with the win-rate math behind each, the rank where each one starts to win and stop winning, and the structure we use on basically every climb order we run across the LoL ranked ladder<\/a>.<\/p>\n
