How Dark Seer and Viper perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Dark Seer and Viper win 48.28% of ranked matches when playing on the same team, over 2,351 matches.
Controlling the map can feel a bit inefficient with this pair. Both Dark Seer and Viper often want to farm the same dangerous parts of the map to apply pressure, leading to some competition for resources. In teamfights, their plans don't always align perfectly. Dark Seer wants to pull enemies together with Vacuum for a big area-of-effect follow-up, but Viper's strength lies in slowing and melting a single hero from a safe distance. While Viper is durable, he isn't the ideal melee brawler who wants to run into the enemy team with Ion Shell, since he does his best work kiting from the edge of the fight.
