I find it easiest if my team let me solo it, as a hunter. If they try to keep up with me I normally take hits from thrall attempting to attack them. I know it doesn't sound like good team play but that's my preference, I don't mind letting them take some free loot :D As for titans, I've seen only one person make it through hard lamps on a titan. He's in my clan and a very good player, I've finished this raid at least 5-10 times per week since release and only seen this one man make it through on titan.
