In FE6, Roy's sword was only on fire when it crit. Make elemental damage from on-hit turn into on-crit. They get a bunch of free damage and it's basically building elemental attack instead of GUI. If their damage is too low, upscale it to make it more similar to critical damage (while being wary of the numbers of stacking both GUI and elemental attack). There are absolutely no repercussions. Ignore the part I said about being wary before.
