Melee – Titan
Yes, every class already has a melee ability, however, why not create a sub-class specifically designed for this. Since we can already use a badass ax and sword, why not make this a permanent staple for a shiny new class. There’s little doubt that Bungie hasn’t had any qualms with letting players dive head first into the fray thanks to the abundance of close quarters items. Having a variety of different melee weapons could help actually define a tank role for Destiny, allowing them to draw the focus of multiple enemies at once.
Given Titans, by design, are the frontline fighters of Destiny letting them act as actual tanks in battle would be quite nice. While Destiny is always an FPS first, infusing more of the RPG roots that it draws from could help add interesting depth and complexity to its combat system. Besides, what Titan doesn’t want to just beat aliens up anyway?
