I wonder how that would work against other arts and just how potent it is.
I assume seeing into the future to avoid an attack still requires having enough reation time to make it out alive.
Atium allows you to see another person's future and process what that means so that you can react with inhuman speed. Electrum allows you to see your own futures but seeing your own future changes your future so you just see a bunch of shadows and can't truly comprehend them all. I guess when your opposition has insane amounts of speed they could move faster than what atium will allow a person to react to. Electrum again is so difficult to comprehend that I imagine opponents speed would be able to surpass it as well.
For chromium feruchemy though, without it allowing you to directly see into the future, would speed increases in your opposition ever get great enough for you to naturally be in the right place at the right time? Also how much do you think thought plays into chromiums ability to work. If you think about making that decision to move would that change the outcome? Or do you have to be almost thoughtless in your moves like the scene when Vin tried to consciously make an unconscious decision?
