replace the sword with the fuel rod, it'l serve the same purpose, completely cheap heavy weapon. Then keep the rocket in the same spot.

Except the Fuel Rod is a ranged weapon, which is pretty different from an overpowered melee weapon.

All that lunging business isn't really necessary anyway, it could just be a fast 1 hit kill long ranged melee weapon and have the same effect.
