We reported last week that a guild named Exodus on the US realm of Ysondre had come out of nowhere to topple the world first of the Heroic: Alone in the Darkness achievement, which requires that you bring down the biggest bad currently in the game, Yogg-Saron, with no help from any of the Keepers in Ulduar. But not so fast, says Serennia over at WoWRiot -- over on their forums Ensidia is claiming that Exodus used an exploit, and that their kill doesn't count at all. Apparently, having Thorim help on the fight keeps the "Immortal Guardians" in the last phase of the fight from being a problem, and without Thorim, you have to not only do the fight without his extra 10% damage bonus (each Keeper ups your DPS that much), but you have to deal with the Guardians messing up your melee classes, and oh yeah: they both heal and get healed by Yogg. Not that it's impossible to do it, but it's definitely not easy, and Ensidia claims that Exodus found a known exploit that allows you to evade the Guardians out completely, thus turning the last phase into a straight tank-and-spank, obviously much easier.
After that, it gets into some guild back and forth (Ensidia apparently did something that might have been an exploit on Hodir, and when people call them out on that, they say that the exploits were different -- Ensidia's tactic was just an interesting use of game mechanics, while the exploit Exodus is suspected of using is more of a cheat), but the fact remains that Exodus is clearly not a guild that anyone expected to clear what might be the toughest raiding achievement in the game before anyone else, and yet that's exactly what they did. Ensidia says they won't be killing Yogg for the achievement using the exploit, and that they've reported the Exodus kill to the devs, so we'll have to see if the devs decide that Exodus did cheat, or if they let Exodus keep their achievements and mounts. We're not sure how much it all matters, with world first kills not being all that important any more (and that's exactly what the devs might say as well), but Ensidia is claiming that an exploit took place -- we'll have to see if that turns out to be true.
