I'm too lazy to read your essays so all I can say is that your wrong. Fire main is useful and his main is basically triggered with debuffs like my personal favs: Blindness, Imprison, and Sleeping. Your probably a low level who fights Higher teams and gets beaten by them with Fire main. Plus since he has immunity to debuffs, transfer debuffs, give debuffs, buff his team, and can heal people when attacking with ninjutsu, it pretty much proves he's useful. Again your probably saying he's useless just by comparing him to other mains.
