I also suffer from visual impairments. My screen is turned down all the way, and I use as much dark background light text as possible. I have problems with the skills and such during boss fights blinding. Blizzard effects are significantly worse. I agree that there need to be options to reduce the brightness of certain effects. If it snows where i live, I can't even look outside without covering most of my vision, because everything else disappears. After a blinding type light, like massive white areas on my screen, the afterburn images are actually bad enough to entirely block out my vision on anything darker than the white. To those of you saying that it's fine to you and it's doing what it intends to do, you aren't taking our conditions into account. It's intended to queue us in to the problem and partially obstruct our in game vision. Instead for many of us, it can obstruct ALL our vision. Particularly if we have a tendency to play or live in areas that are dim to start with. A game effect shouldn't be effecting our real life senses like that.Saying what you do about, it works for me, so it should work for you, is akin to telling a hand amputee that because you can use WSAD the controls don't need to be modifiable because they work as intended without a problem. And that because you can use it, the game doesn't need joystick or accessible controls support. Like seriously. Take a moment and actually think about how OTHER people are affected by those things. We aren't asking to have it removed changed, or to turn off YOUR immersion or gameplay. We simply want to be able to make personal modifications that let us enjoy it as well as you do.
