Most Useful Heroes in Final Fantasy 15: A New Empire

I rank the heroes in terms of most useful and helpful moving forward and progressing through the game. General purpose utility. 7) Prompto: Great for leading city assault attacks, particularly through rallies. Needs medals before level 50. 6) Aranea: Strong cavalry boosts and good for mercs but not as good as Ravus or Gladiolus. Also needs dragoons to be real effective 5) Ravus: Good attack boosts, 100/200 free t7 mercs every day. Needs banishment portal active and prisoners for best effect. 4) Gladiolus: Free 1/2 commanders every day. Training speed, warrior buffs, attack steal and massive attack buff if sufficient Armor. 3) Luna: 2x luna gifts!! Good defense and crystal capabilities, mage buffs, cheaper than ravus, gladiolus, and aranea to level. 2) Noctis: March Size, Rally size!! Great for crystal, rallies, rvr's, invasion events... you name it. 1) Ignis: Research cost savings on resources and time! double loyalty, siege buffs, troop attack buffs, airship buffs, converts research speed into attack. Oh and he can make 1000000 traps :D
