Head-to-head Dota 2 7.41f win rate from ranked matches.
In Dota 2 7.41f, Dazzle wins the Dazzle vs Io matchup: Dazzle beats Io in 51.98% of 10,638 ranked matches.
Trying to burst an Io-tethered core often feels like the right move, but Dazzle's damage output struggles to overcome the constant healing and the fight stalls. Conversely, a well-timed Shallow Grave can completely negate a Relocate gank, buying crucial time for a counter-initiation. The matchup really hinges on which support can bait out the other's critical save first. Io's ability to be anywhere on the map can put more pressure on Dazzle to be in the right place at the right time, which is not always easy. Because both heroes excel at keeping one specific ally alive, they tend to cancel each other out, making team execution the deciding factor.
