Deadly! Raging Blow!!

Naw. Both weapons are pretty much the same thing; both are bladed weapons. Gun and sword? Ranged and melee? The skills to accommodate both weapon styles are going to be a beeyatch to create/animate so they'd mesh well.

Mercedes and mechanics have both close and long range skills (although mechs are more medium-range than close.) e.x. rising rush and skill combos on mercedes in spite of being archers, and atomic hammer on mechs. They can make close+long ranges work...
