Many class talents, spells, and abilities have been overhauled, added, or removed.
All spell and ability tooltips will now display damage averages rather than minimum and maximum damage potential. This feature is on by default but can be changed via the Display settings under User Interface options.
Ammo has been removed from the game.
The character levels at which classes gain new spells and abilities have changed.
Many item and class stats have been changed or removed.
Mastery rating has been added as a new stat which provides unique benefits for characters based on class and talent specialization. Mastery rating does not currently exist on items in the game, however, Reforging can be used to add Mastery rating as a secondary stat to existing items.
Rage has been normalized.
Spells and abilities no longer have multiple ranks and now scale with character level.
Talent trees have been altered. All player talent specializations have been reset, allowing for free re-specialization.
Each specialization has been reduced to a 31-point talent tree.
Players will now get a total of 41 talent points to spend.
Players will be asked to choose a specialization at level 10. Doing so will result in the unlocking of a spell or ability unique to that specialization, as well as one or more passive bonuses.
Once a talent specialization has been chosen, players may only place points in the primary tree until at least 31 points have been spent there.
