I recently watched a bunch of ~2000SR replays with a friend and I found it physically painful to watch some of them from the 1st person perspective of players with high mouse sensitivity. Totally jerky camera rotations.
Some of them were ana players: on one occasion ana couldn’t save a moira who was lifted by Sigma’s ult because one of the shots missed on moira’s left side while the second missed on her right side. That was a stationary target… Imagine what’s going on when people are running/jumping around.
I wish there was a “camera rotation smoothing” option while observing these players (at least in replays).
