More dmg with or without more range is badly needed on FoI! Also the weapons supporting elemental FoI need better conversion, like full fire to lightning and full lightning to fire respectively. E.g. flamestrife should have at least ~50% lightning to fire conversion or one could increase the amount of global conversion that eternal pyre rings give.
