It does indeed seem as though they'd make a good pair in a fight, but I feel as though we may need someone speedy to come in since both the great sword and gunlance tend to favor high damage output over swiftness. Excellent when dealing with the beefier, slower monsters, but not quite as useful when facing something as quick as a nargacuga or as sporadic as tigrex. With any luck someone may come in with dual blades or an insect glaive to add a flurry of quick blows to the mix in between the strong blows.
