Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Arc Warden wins the Arc Warden vs Io matchup: Arc Warden beats Io in 50.20% of 3,494 ranked matches.
Picking Arc Warden into an enemy Io means you have to play with a constant fear of Relocate. Arc Warden wants to sit in one spot and farm, using his Tempest Double to pressure other lanes, but Io can bring a carry right on top of the real hero at any moment. This can force safer, less efficient farming patterns. In teamfights, Io's ability to heal and buff his Tethered partner can make it difficult to secure a kill, even with both Arc Wardens focusing a single target. The advantage isn't overwhelming, though. Io is fragile and easy to burst down if you catch him, and a Relocate gank is only as strong as the hero who comes along for the ride.
