This may sound hilarious, but I think Torbjorn is better on attack rather then defense now.
A night or two ago with some friends we decided to do QP and I asked them, just for giggles, if I could play Torbjorn on attack. Went into the game, Hollywood, and they were beating us at first, but then we pushed through and I got a turret up and they were unable to take Point A back. Once the point capped I ran over to the car and put my turret on it, then stood to the SIDE of the car and hammered it as it moved, the other team unable to get the focused damage together to kill it before I could heal it, and unable to hit me behind the car. We steam rolled all the way to the end and they finally got me around the last bend, so I went to the side and put up a turret there after respawning, taking them totally by surprise, and we won. I got POTG and a 4 gold medal card, it was hilarious, and my friends couldn't believe it.
So tonight I decided to join another QP, just totally solo, and got Route 66 attack, so for laughs I picked torb again, the team even said in voice chat, "really? A torb?" I pre-setup a turret in the room that looks right out to the payload, then ran up the left side to the upper cliffs, placing it right above the enemy. It killed them all, so then I did the ride and hammer again. We had just hit the second checkpoint when the enemy Dva ulted right on top of me, but I was not going to just lay down. I ran in the left side into the warehouse and up to the moving platforms, placing my turret on one and riding it all the way across, getting kills the whole way. When I reach the end I am on that little platform just above their spawn room, so I jump off and place my turret there, shooting them in the back any time they came out, and they couldn't target me while I hammered on it, leaving them so distracted my team obliterated them. We won and I got another POTG while riding the payload. My team was like "holy shit".
Those teams turned into a 3 series of games, so next we did attack eichen, and I actually picked Winston, but my team was like "no dude, go torb", so I did. I used higher side paths to get up turrets and forced them back, we took the point but this time they were focusing better on the payload, so I ran around the side to the upper bridge and put my turret up there, right behind them, killed the weaker ones then jumped down and obliterated a Zarya with my alt fire. Funny enough in this game the Dva ulted just me to get me to hopefully stop, but it was too late, my team got the second checkpoint. As I respawned and ran inside I stayed to the upper castle stairs, knocked out the rails and put up my turret, which forced them to hide around the corner at the final objective point, so I rushed the corner and literally walked into the alcove the Tracer and Lucio were hiding, those shotgun blasts were sweet. I quickly ulted and hammered up my turret in the alcove, and it was over. I didn't get POTG that round (it went to a Reinhardt on my team for an amazing quad kill before Point A), but my team literally said "thank you for all those armors, daddy torb!"
Final game of the night was defense, same teams, and the other team decided to do the two tank, two healer meta. We started okay but they overpowered us, me unable to keep my turret up very long since they now had a Reinhardt defending the offense and the healers keeping him and the Dva alive. I mean seriously, my turret up-time from offense to defense was like night and day. They ended up pushing us all the way to the castle so I decided to switch it up to Lucio, and danced the payload to keep them from moving. We ended up winning on the final bend because they just couldn't kill me, and boy were the other team salty for those losses.
It was on that the matchmaker ended the teams, so I decided to just end on a high note.
