I was in one of the first 20 guilds to kill KJ and I think it is a great thing they nerfed it so all the casuals can see content. I actually stopped raiding a few weeks after downing KJ and didnt raid again till recently. It has made this stuff even more fun than it was the first time round for me because I get to see it and have a laugh with my real friends who werent into spending 6 nights a week raiding. The first kills of bosses where a great achievement but the amount of stress they caused on not just me but my real life relationships made me think twice about ever going that route again.
