How Primal Beast and Viper perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Primal Beast and Viper win 47.46% of ranked matches when playing on the same team, over 2,265 matches.
Stacking Viper's slows on top of a Trample seems like an obvious way to lock someone down, but these two heroes often want to play the game at different paces. Primal Beast is a hard initiator who wants to charge deep and cause chaos, scattering the enemy team. Viper, on the other hand, prefers to fight on his own terms, kiting enemies and controlling a specific area with Nethertoxin. Their ultimates also create some redundancy. Using Pulverize and Viper Strike on the same hero is often a waste of lockdown, leaving your team without a second major disable for another priority target. They end up doing the same job instead of cleanly setting each other up.
