I think this is a bad idea, albeit I supported nerfing the bracers...well that nerf was a bit extreme but still.
37% reflect field that will be possible after the patch is far from being overpowering and should remain as it is.
I think RRFE should stay as a buff that soldier can give to the team. However...
I think soldiers and engineers alike should have access to better buffs themselves, perhaps 50% self-only RRFE would be in order. This is a similar thinking then with MA crit buffs, self only are much more powerful then those you can give to other now after all you as a MA/soldier/engineer should be an expert of that specific field hence you should be a master of it.
