Wowhead has released some class guides written by knowledgeable members of the WoW community, with a focus on being fast and easy to get information for new players, boosted 90s, and alts or offspecs. If you want some quick answers to basic questions, your best bet is right there.
If you have questions about the Enhancement guide, I’m the one to contact. If you see any errors or have information to share or have any other kind of feedback, let me know here or leave a comment on the guide itself. We’ll be keeping these as up to date as we can.
