Tinker vs Witch Doctor

How this matchup plays

Drafting Tinker when Witch Doctor is available for the other team is a huge liability. Witch Doctor’s kit directly counters what Tinker wants to do. A single Paralyzing Cask bouncing from a creep is enough to find Tinker in the trees and interrupt his Rearm, completely halting his spell rotation and leaving him exposed. Even if he blinks away after taking damage, Maledict ensures any follow-up from across the map can be lethal. It punishes the exact hit-and-run style that Tinker relies on to survive engagements.

This pressure forces the Tinker to play reactively all game. He can't safely push lanes or join fights from the edge, because Witch Doctor is always waiting to lock him down. During teamfights, Death Ward can control the exact area Tinker needs to play in, forcing him out entirely. Tinker’s main recourse is an early defensive item, but that compromises his own timing and damage output. Meanwhile, Witch Doctor builds his normal items and continues to be a massive threat by existing on the map.
