Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Arc Warden wins the Arc Warden vs Viper matchup: Arc Warden beats Viper in 58.23% of 407 ranked matches.
Trying to convert a won lane into objectives is where things fall apart for Viper. Once Arc Warden has his Tempest Double, he can be everywhere at once, constantly shoving lanes from a safe distance. This forces Viper to react to pressure all over the map, a role he is not suited for, as he lacks the mobility and wave clear to deal with the split-push. In a direct teamfight, Arc Warden can place a Magnetic Field to completely neutralize Viper’s physical damage from range, forcing him into a terrible position. Viper is also very susceptible to being controlled by two heroes at once, and his single-target focus with Viper Strike is easily wasted on the clone.
