In Dota 2 7.41f, Storm Spirit and Io win 45.06% of ranked matches when playing on the same team, over 9,024 matches.
Trying to set up a gank with Relocate often feels awkward for this pair. Storm Spirit already has Ball Lightning to close any gap, so he doesn't need the tethered movement speed as much as a melee core would. The real issue is the lack of instant lockdown. Once they arrive, Storm has to get close to use Electric Vortex, which gives the target a moment to escape or use a defensive item. Io can't offer a stun to guarantee the kill, making their signature gank combo surprisingly unreliable from the start.
This dynamic leaves the enemy team with a clear plan. They know that if they can survive Storm Spirit's initial jump, the threat is manageable. Teams will focus on silencing or bursting Storm, as Io provides no real save against that kind of instant aggression. If the gank fails, both heroes are left in a bad spot; Io is fragile and easily killed, while Storm is forced to use a huge amount of mana to get away safely. The duo struggles to secure the early pick-offs they need, often leaving them playing from behind.
