Head-to-head Dota 2 7.41f win rate from ranked matches.
In Dota 2 7.41f, Viper wins the Bristleback vs Viper matchup: Viper beats Bristleback in 53.68% of 37,804 ranked matches.
Trying to run at Viper seems like a good plan for Bristleback until the fight actually starts. The whole engagement often hinges on Viper's placement of Nethertoxin. Standing in that pool disables Bristleback's passive, turning off his signature damage reduction and making him surprisingly fragile for his own team and everyone else. The constant slows from Viper's attacks and ultimate also make it tough for Bristleback to turn his back to reduce damage or simply run away. He either has to commit to a fight where he's at a disadvantage or back off entirely, giving Viper control of the lane and later skirmishes.
