Spectral Stats - BTS Pro Series - Heroes - Counters

Explain this to me

The page shows a hero's winrates against certain enemies, as well as winrate advantage (difference in winrate compared to overall value). Higher rank and winrate mean opponent is easier for the hero, higher R-Rank means opponent is picked often and is less effective against the hero.

	Hero	Matches	Winrate
	Io	6	66.67%

Remove low matches (1) Only positive winrate diff
