Yeah 95% of the plays of the game are either Bastion hiding in a corner shooting people or ulting and shooting people.
I managed to pull off a Play Of The Game as Lucio, but I had to go full offence to do it. With Torbjron it's easy. The algorithm seems heavily biased towards heroes that can get a quick succession of kills, which turret classes excel at. I know it's harder to evaluate the contribution from support or utility classes, but it's pretty lazy design to just measure multi kills.
So funny especially when they've just popped their ult - "Seeya later sucker!!!"
