I get pretty good ganks with Torturer. Main reason being almost all his damage output is AoE. Early ganks are easily done with his stun and opponent thinking they can kill you quickly because he's a squishy character. Harass the fuck out of enemies in your lane, if they go to initiate or one of the laners goes solo, stun and follow them around with AoE. This can go horribly wrong if you time it wrong ofc, but easy character to figure out when to do this.
