Head-to-head Dota 2 7.41f win rate from ranked matches.
In Dota 2 7.41f, Io wins the Storm Spirit vs Io matchup: Io beats Storm Spirit in 52.99% of 10,729 ranked matches.
Picking Storm Spirit into an Io feels like a gamble from the draft screen. Storm wants to find a solo target, zip in, and secure a quick kill before anyone can react. The problem is that Io's entire kit is built to stop exactly that. A single Tether can give a target enough survivability to withstand Storm's initial burst. From there, the situation gets much worse. A well-timed Relocate not only saves the victim but can also bring in a counter-gank right on top of an out-of-position Storm Spirit. He commits all his mana for a kill he can't secure, leaving him stranded and vulnerable.
