I have all three characters (hunter, Titan, warlock). I've done the raid of all of them. I can tell you now that what matters is skill, not class. If you are experienced and don't die, then you are helpful. Warlocks with resonance have it easier because they can resurrect often. No other class has this. I've played with teams full of warlocks and teams without a single one. Firstly I'd like to say that the raid is so much more enjoyable without having to cheese it. If you're a hunter, you have it better off because you are more likely to have fun in the raid. Cheers!
