I was thinking Just Cause and Attack on Titan with the grapple Idea, and a bit of Zelda. I was thinking about doing three dark or Kinetic subclasses just for fun, one for Titan, Hunter, and Warlock. If swords and bows aren't going to be weapons they could be melee abilities. So Titan would get shield or grapple, Hunter would get bow, and Warlock would get a katana like sword. The grenades could be different arrows for the bow or something like it. I'd rather have a bow as a weapon though.
