Discord is the new voice program taking over many gaming communities with its crisp, free voice-chat and very useful text channels (EDIT: see this list of Discord channels for Legion). There are several community-run wow-related discord servers, including this one for WoW in general and these for each class. Check these channels if you want to stay tuned for the very latest theory-crafting. You can also make a free server for your guild. http://www.wowhead.com/: Wowhead, already very useful in general, seems to be stepping up its class guides game for Legion (navigate from http://legion.wowhead.com/guides/classes). http://www.icy-veins.com/wow/class-guides - A very reasonable starting off point for class guides, with the best guide available for some specs. The Icy-Veins forums also have bits of useful discussion. http://www.mmo-champion.com/: This site, like wowhead, has periodic updates about wow, as well has having very well-trafficked forums, which have the best theorycrafting available for some classes. http://www.reddit.com/r/wow/: This reddit subreddit is an official wow community site and has good, active discussion about wow. http://www.reddit.com/r/CompetitiveWoW/: This reddit subreddit is narrowly focused on high-level wow raiding. There are detailed guides, log analysis posts, and more. http://simplearmory.com/: This website allows an alternative view of the wow armory. The collectibles, mounts section links to a good guide for mount farming and tells what you missed at a glance. http://bossblueprint.com/wow: This website is a great way to quickly outline raid positioning strategies for HFC.
