While you're at it sir, it's not just this gun. I don't think I have found a single gun or ability that doesn't cause blinding light scenarios.
It's at its worst in darker areas but it's a general thing from basically anything that creates light and explosions.
Even the lights on my Colossus' armor are like I would look into an actual light in real life.
After every mission I basically have to take a 10 to 15 minutes brake, or I get massive headaches, which alone is doable but if you play with friends, you can't just make them wait that long after each mission.
I don't have that problem in other games nearly as bad as in Anthem after that short amount of time. Maybe slightly when I played something intensive for 5+hours but not after just one 15-30 minute mission.
