For context, Flash, with the large scar on his arm had an elo rating in brood war that may have made him the best player of any game -ever-. I think I've seen it noted somewhere that his highest elo was higher than even famous chess grandmasters.

This implies that after over a decade of hardcore professional broodwar around the world, he was more dominant at his peak than anyone else has ever been in a game with elo ratings.
