For the reference-minded among you, we've compiled a Burning Crusade reference guide for you, your alts, or anyone new to BC content to use as a handy, one-stop-shop reference. The guide aggregates the most informative links we've found on BC-specific content so far, including dungeon walkthroughs, profession and class changes, new PvP objectives, maps, quests, loots, changes in patch 2.1, etc. We hope you find it useful, and we hope you'll help us continue to improve the guide by making suggestions in the comments here of any other Burning Crusade-related guides, FAQs, walkthroughs, or roundups we haven't yet included. We'll do our best to check this thread and add updates to the guide with your contributions.
