There's things they need to tweak with every single subclass, and they need to figure out what each class, as a whole, is supposed to represent. At present, the subclasses and classes are starting to have little to no diversity between them, and it seems like the stronger they perform in the areas where meant to Excell in, the more bungie wants to nerf them and "bring them in line with their game." The way I see it, as well as a majority of the community, is that the three classes are suppose to represent the cliche Rogue/tank/mage builds. Hunters, the rogues, are supposed to be fast, light on their feet, quick in all areas, and out put incredibly high damage per second. They prioritize speed, high hit rates, and ranged combat. Titans, the tanks, are supposed to be able to play point, eating damage as the go, and being able to put out huge amounts of damage in a single hit. Close range combat is their specialty, and they don't care much for speed. They prioritize health and single, accurate hits on areas to break through the lines. Warlocks, the mages, are supposed to sit further back even than the hunters, buffing the team, debuffing the enemies, and dealing large amounts of damage in sporadic bursts to groups of enemies to bring them within range for the finishers. They prioritize the ability to watch and wait for the right chance. But, while it [i]seems[/i] like this is already happening, look at the actual state of the game.. The titans have literally all of that, and the warlocks can do most of it, while the hunters fall behind. The latest update really threw this off. They need to fix it.
