Been trying kenrethad all week, starting the day the tome could be dropped. No luck killing kenrethad all day. Currently 477 ilvl and I've had LFR on farm since I returned to WoW. I've got keybinds, macros, and 3 years experience as a lock but once I get to the fel hunter phase I always slip up on something and usually get killed by cataclysm or a chaos bolt. I have had at the least 60+ encounters done, the farthest I have gotten him was 40%. Its just not happening. It feels a tad bit overtuned but it might be just my gear.
