Petition: turn 180° and kill training mode

Hi. New Roadhog and Tracer buffs have made me think about the need of training reflexes.

Tracers usally pick my backside to farm her ult, so I am (well… was) used to turn 180° and hook them. I use this “tech” to disable some ultimates to.

However, Tracers with the new buff can fire from 3 metres further tham before, so I have to be more precise in order to hook them.

Do you know of there is a workshop mode in which I can continously train the “turn-180° and fire” tech? I was thinking in a mode where bots spawn just behind you.

Thanks.
