If they are leveraging the targeting ability to do massive reliable damage from sneaky ranged angles, that’s a skill that can be learned by anyone that has patience and map knowledge. If they are running Torb as a close range burst with Overcharge and tight coordination from their Supports, that is a knife-edge boom-or-bust style gameplay that will be difficult for mere mortals to emulate.
My two cents as a mere mortal.
Still, happy to see him get pro play. Hopefully the tactics will trickle down and the prejudice will wear off.
