The contents herein are entirely player made and in no way represent official World of Warcraft history or occurrences which are accurate for all realms. This page includes a list of guilds that have accomplished a particular task (usually by defeating a major boss). The list should not be taken to be 100% accurate, as it only contains data that has been submitted/added by users of the community. Thus, if you have information you can add, and contribute to the list, it will become more complete.
Guilds are listed by overall progression, then by alphabetical order. Let there be a distinction drawn between a collaborative effort and a run. Please do not add kills that your guild was a part of but was not a collaborator in. A collaboration would be if two guilds group their members together to progress and both sides contribute substantially. A run is if one of the top guilds on the server were to run 5 members of another guild through Naxxramas.
Several guilds with smaller rosters do PUG with friends and others to make progression happen. Due to this, any run that is comprised of guild members totaling at least 80% of a raid will count as progression for that guild. For example, if a guild is running 25-man Naxxramas and brings along two friends from outside the guild, this kill will still count toward the guild's progression. If a guild was to bring along fifteen guild members, then ten non-guilded friends, this would not count as guild progression.
