I actually have a separate idea for the other classes. Warlocks are supposed to be the "Mages" of the game, so giving them spells makes sense. Hunters will be able to collect different Melee weapons, like swords, knives, daggers, hatchets, ect, and normal Melee knives so you don't have to use the same general knife with each strike. These weapons would give Hunters different perks for different usage purposes. Hunters are the skilled assassins, the adventurers, so energized ninja weapons will fit them. Titans, instead of getting normal weapons, would get more armor gear. Some gear would allow them to take Shoulder Charge to the next level, be able to tank so much damage that it will require two rockets to kill them, and increase melee attacking power, like brass knuckles charged with solar energy. Titans are meant to be the tanky damage dealing class of the game, so this would fit them well.
