Nononono not some crazy thing like rocket launchers (though a chainsaw-rocket launcher would be friggen awesome). Well, perhaps something just as crazy and probably unaccepted here...

HALBERDS!

Well, pole-weapons. Simple: Melee-ranged type weapons. Like swords they do combos, but can deal damage up to twice the range of swords. Obvious OP is obvious, but a balance could be that you can't hold a shield. Or, be like the T3 gremlins and have the shield on your back so your back is invulnerable but your front is. Also, there's always other factors that can be nerfed such as the speed, strength and mobility. Nonetheless, I'm a Knight who likes using halberd-like weapons just cause they look awesome and ARE awesome.

Halberds can be the slice-type pole weapon whilst Spears can be the pierce-type pole weapon. Use your imagination from there (you know, a brandish-type halberd that can branch out to shadow or elemental damage, etc).

Ideas for charge attacks? Uhh. For halberds there could be a wider-than-normal vertical slice forwards and then a second one right after. For spears, perhaps a charge forward with spear in front. Why not?

:D?
