How Arc Warden and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Arc Warden and Io win 51.41% of ranked matches when playing on the same team, over 2,943 matches.
Picking an Io for Arc Warden seems promising on paper, but their core mechanics often clash. Io wants to be Tethered to a hero diving into the fight, providing heals and movement speed. Arc Warden, however, wants his real body far from danger, using his Tempest Double to do the dirty work. This leaves Io in an awkward spot: he can Tether the real Arc Warden who isn't in the fight, or he can go help another teammate, which defeats the purpose of the pairing. While a Relocate can help the main hero farm or split-push, the lack of combat synergy with the Tempest Double means you lose a lot of Io's teamfight value.
