I liked kings fall. I didn't like people who die for no reason all the time, and people who don't understand "counterclockwise". I didn't even play King's Fall for the entirety of year 2, only the last few months of it, and I still got tired of doing it. In fact, I've already gotten tired of doing Wrath of the Machine, which is also a good raid. In both cases it's not the raid that's tiring, it's people on lfg who suck that get tiring.
