Nerf of FE is still not enough - most broken card of that archetype - candle - is still alive and well. Even failed experiment was not as broken as that is without artifact removals, so the core of problem of that deck is still there. The reason it is not played as often now is only the swich in meta - not many people play tall units now, rather wide play with dmg, a lot of special cards in the meta ( like tactics) , decks like NR knights are not played now almost at all. If candle wond be nerfed or reworked or artifact removal restored, toxic SY decks like GN poisons will be back to meta sooner or later - unfortunatelly
