while the idea of having grapple points is a good way to have grappling be aviable without a grapple gun and also be able to shoot, I have a better idea: duel welding! Just imagine it, it'd be amazing! and you'd have a use for the right mouse button, because it could be used to fire your second gun! you'd still have te privilege of grappling wherever you want, but won't have to worry about losing your ability to deal long-range damage!
