Simply put, Hunter perks/skills rely on player ability (e.g. Gunslinger's Trance, Chain of Woe, Knife Juggler, Fleet Footed) as well as situational intelligence (e.g. Escape Artist, Shadow Jack, Stalker, Tripmine Grenade). They're the most difficult class to excel with because they don't offer the same AoE supers/grenades the other classes employ. Everyone else has situational skills as well, but no other class relies as heavily upon them to find success in both PvE and PvP. They're better than most classes (with the exception of a fully armored Titan) in 1v1 encounters, and if Hunters have excellent map awareness, their mobility can be annoyingly deadly in the Crucible. I feel more accomplished after using my Hunter (main) in PvP than I do with my Warlock (who gets easy kills with Axion Bolt and a panicnade Super) even though I usually do better with a Warlock. Ultimately, I agree with your assessment that Warlocks are probably the "best" class in that they're the easiest class to find success with (and their Exotic builds synergize amazingly well; Bad Juju + Obsidian Mind is OP as -blam!-). They're the most user-friendly, offering more mobility than the Titan while retaining amazing AoE abilities. When my casual friends jumped on Destiny, the Voidwalker Super was too good for them to pass up and the rest is history. But we all know subclasses/classes don't make the player, so everyone can play how they want. There are just as many clueless Warlocks wandering around as there are Hunters who don't know when/how to stealth kill.
