EJ is still the best tho if you want to know in-depth about your class + running sims on your gears. If you have intention to raid in semi or hardcore guilds, understanding your class is much more important for max dps in any raid situation. Hunting around for simple priority/rotation/gear/chants wont bring you far.

Use the ingame loot, atlastloot addon or wowhead.
