I can understand this, however, like you said... we are all different. There has been some people who have already had health issues arise-- and I've already dealt with bad headaches & migraines. I just edited some footage of it, too, and I'm now needing to take a break just by trimming the videos.
And to be honest, if they did disable it now, and then put them back in the future, you can still use them all year. You just wouldn't be able to buy more.
And for some, the white flash from the snowballs, take up the entire screen. Esp if something happens [like a button gets stuck, or the game for some reason registers it as this]-- can make it happen rapid fire & make it larger. I've had it where it thought I threw two or three, and it just increased the intensity. :[
