Hunters are definitely the most skillful class to play, and once you master it you can become an absolute beast. With a combination of tactics, stealth, and proper gun-play, Titans and Warlocks are just fodder beneath the wrath of a Hunter. I can't count how many pleb Titans and Warlocks I've killed with my amazing Golden Gun -- truly they are no match for my superior skill. I imagine some Warlocks and Titans are rather frustrated since they are not as good as people who play Hunters, so my only response to that is: git gud.
