The strongest nerf for Tinker is that the laser is boosted by mana as well as the Soul Ring is slightly nerfed. If there is a weak Tinker stage, it is definitely early in the game when the hero is not able to escape and rely on Laser and Soul Ring to stay lane only. And when both of those factors were reduced, Tinker's early game was a bit tilted and Tinker's win was down from around 50% to about 47.6%.
