During BlizzCon, Blizzard announced two new core features that are on their way to World of Warcraft in The War Within - Warbands and Hero Talents!

Warbands

Warbands are a new feature that allows you to link your characters together so that you can share your reputations, banks, and even transmog. You'll see your Warband on the login screen.

Expand the potential of your alts with account-wide progression across your family of characters on your Battle.net account, regardless of their Faction. Share Warband Bank access, War Within Renown, achievements, collections and more.

Hero Talents

Rise to new heights of power with new Hero Talent trees! Each class specialization has access to two choices of self-contained Hero Talent trees inspired by iconic Warcraft universe archetypes.

We got a preview of what is to come for Balance Druids: Keeper of the Grove & Elune's Chosen.
