I like being able to see my surroundings to a greater extent, but if I see space that is enemy-free, I generally assume there are no enemies there. I think it will be a little disorienting to have enemies suddenly render partway across the screen where there once wasn’t an enemy, and at the moment I can’t see myself using this.
Of course, this reaction is similar to the one I initially had about turning off allied projectiles and damage text, so my opinion could very well change.
