Well, I was thinking about dual wield... and I know most of the reasons it hasn't been implemented but I had an idea for including it!
After we get a Xenia model, if that ever happens, we should have a mode called "Xenia's Revenge" (name up for debate) that plays sort of like MWGG except one person plays as Xenia and dual wields a grenade launcher and an RCP90.
Anyone second this idea?! xD
