The beta stops at level 30, so "best in slot" right now means the best gear you can get at 30. The lists below come from Wowhead's beta Fury guide, which was written from hands-on play. We list item names only; check stats in-game, because Blizzard is still retuning quest rewards (the 26 Oct notes corrected the item level of several). Wowhead's Fury table also lists a Razorfen Kraul item whose name didn't render on their page, so we've left it out. [Unconfirmed] The Whirlwind Axe chain includes an elite and materials from Stranglethorn and Arathi, so check that it's really reachable at 30 in the beta. [Unconfirmed] We haven't found sourced lists for Arms or Protection.
