Theory for new Bruiser, fighter Keystone "Double edged sword"

While remaining in combat, Damage you deal increases your resistances, and health (scaling with resists, and health), and damage you take increases your adaptive damage (scaling with adaptive ap/ad) as the fight progresses.

This allows all fighters to become blood hungry in a fight so not to lose the build-up of stats that accumulate for getting hit and hitting champions. It fits perfectly to what a fighter wants to be doing, and most of all, It would super fun to build and play fighters as they are meant to instead of half tanks, or semi assassins. Bring back glory to the fighters. :)
