How Kez and Viper perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Kez and Viper win 44.85% of ranked matches when playing on the same team, over 330 matches.
Trying to take a mid-game teamfight often feels awkward. Both Kez and Viper excel at isolating and wearing down a single hero, but this leaves the rest of the enemy team free to act. Viper's slows from Viper Strike can help Kez stay on his chosen opponent, but neither hero brings the hard lockdown or area-of-effect control needed to manage a full five-on-five engagement. The draft ends up with two cores who do a similar job without covering each other's weaknesses. While Kez is farming the items he needs to duel enemy carries, Viper is often past his strongest power spike, creating a timing clash that's difficult to resolve.
