I have MH4, and the Insect Glaive is already nerfed to the max, and they most likely added the hammer upgrade because it does not have a new move in MH4, while most other weapons do. Great sword has the mega swing after the mega charge, Long sword has a spirit slash after the jump back swing, Switch Axe has a double swing in Sword mode, Bow has a new Arch shot called a hard shot, which is a normal shot that can be combined with a normal shot, Hunting Horn has a double swing with the secondary note attack, Sword and Shield has a new combo, which you jump back and recontinue the normal combo. The only weapons that don't have a upgrade are Dual Blades, Both Guns, Gunlance, and until now, Hammer.
