How Naga Siren and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Naga Siren and Io win 47.01% of ranked matches when playing on the same team, over 1,172 matches.
Tethering the real Naga Siren seems helpful, but it instantly reveals her among the illusions. This makes it extremely easy for opponents to identify and burst the real hero, negating a core part of her survivability. The game plans can also feel at odds. Naga Siren often wants to farm safely and split the map with illusions, while Io looks to enable aggressive, early action with a core. Using Relocate to force a fight can pull Naga away from crucial farm before she's strong enough to contribute. Even a good Song of the Siren setup may lack follow-up if Io is the only hero present, leading to a pairing that often works against itself.
