How Primal Beast and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Primal Beast and Io win 47.73% of ranked matches when playing on the same team, over 2,491 matches.
Pairing Io with a brawling front-liner seems solid on paper, but the results here are often mixed. While Primal Beast appreciates the Tether movement speed to line up a good Onslaught, he gets very little out of Overcharge's attack speed bonus since most of his damage comes from spells. Relocate ganks can certainly work if the Beast has Pulverize ready to lock someone down on arrival. The main issue is that Io's kit doesn't directly feed into what makes Primal Beast a menace. It provides general survivability and mobility, which is useful for anyone, but it doesn't create a special advantage the way it does with other cores.
