Pro presence and win rate by role, from real game data — weighted by source, region, and recency (so KR / tier-1 / current-patch games dominate). Win rates are empirical-Bayes shrunk so small samples don't spike the list.
Ranked by wins above pre-game Elo expectation (not raw win rate), so a champion that drags weaker teams to wins outranks one that only wins for superteams.
