After reading all the above, I feared to try. I am a ranger, 75, and solidly raid geared. I also tossed everything at it, fully self-buffed, Steadfast Servant, SoE for sure, Infusion of the Faithful, HoT, etc. After clearing the nearby mobs, I harmonied the last one and dotted Skyrake and after he summoned me, he tossed me way way way up in the sky. it took me about 20 seconds of spiralling down to get back to him, and I was already down 40%. Weaponshield up and attacked and chain nuked. He died in about 30-40 seconds of that, and my healing about equaled his spell damage. WS may have dropped before the end, but not by too much. Still around 50% health at the end. The final drake never added.
Oh, he definitely moved some, but I'm not sure how much. As I was spiralling back down, he ran to stay beneath me and also to attack once I got down. We finished far enough away from that final drake not to aggro it.
