This is a Rein problem. Orisa’s barrier doesn’t stay up long - usually 2-3 seconds at a time, and Sigma’s barrier is mostly on the move so it is not always in front of you (unless you’re widow and you deservedly get it in your face). Playing against a Rein is just tedious, especially on maps with a choke that his barrier completely fills. Sure you can break his barrier but it is the amount of time you are alive that you spend shooting it that is the problem.
I wish they would have hero pools in QP just so Rein could be banned every 2nd week! The other day I had Rein in the other team in 15 out of 16 games (some of them started without him but switched when losing). The last couple of months have been horrible with Rein in so many games.
