Immortal Rank Meta Trends - 7.34b

Stats for matches of Immortal rank players, data provided by Stratz.com

Average number of buybacks per game by Dire: 0.7215

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.
