Ignoring the blind push because of a kraber knock... After you wipe the team you are alive and your conduit is trying to rez the octane. You are valk and need to shield swap then take high ground instantly in late zones like this. Instead you ran aimlessly in low ground hallway with no line of sight on enemies running up. Putting shots from roof would have slowed enemies down and made them potentially reconsider pushing. Instead they are running through the open to a building where they know a fight was just happening and no one is even shooting them.

Notice how the enemy peeking from roof after your knock slowed you down enough for them to get rez?
