+1 for the GitM and C42 weapons... +0.5 for the LoA weapon.
A Piercing Winmillion wouldn't be the most useful thing, because Wolvers, Devilites and Gorgos are tricky to hit at range. Maybe that Almirian Spear could be... Shadow/Shock to parallel the Shadow/Freeze Handguns? Or maybe make it like Iron Slug and have it be Normal with high Stun chance; after all, Legion of Almire has somewhat of a Stun-theme going on, so that would make sense.
Though, here's my biggest gripe with this idea: if Maulos' Fury was hammer-styled, unless its damage was neutered compared to WRH (which would make the weapon worthless), there wouldn't be much reason to buy the DLC and go after WRH. The reason there's only one hammer is because once you master the playstyle, it becomes a godly weapon, and so they had to make it a DLC mission reward. I think making it Troika-styled would be better? A type-damage Troika would be nice, anyway.
Other than that, these seem like some really cool weapons. Good job with the naming, too.
+1 for all of these
IMO the Maulos fury shouldn't be crafted up from a PVP recipe weapon. Still a bit hesitant about putting freeze on it, would be fine if it was just the charge but if it was on the regular then it would be OP since you could freezelock enemies on PVP.
