Stats on equipment and how they affect the different classes has been altered by the Shattering. Basic stats such as Attack Power and Spell Power have been completely removed from gear. Now, only Paladins, Warriors, Bear Druids, and Death Knights can gain Attack power from Strength; Rogues, Hunters and Shaman gain Attack Power from Agility. Spell Power is completely controlled by a character's Intellect.
Mana Per 5 Seconds has been removed and now all Mana recovery is directly controlled by Spirit. Various builds of Shaman and Druids will also gain Hit Rating from increased Spirit. Haste will now affect the regain rates of Rage, Focus, Runes and Energy.
Armor Penetration is no longer a stat featured on weapons or other gear, but may be acquired with certain talents or training. Defense has been reworked, including the removal of Defense Rating and Defense Skills. Further, Block has been redone to provide a base 30% damage reduction. Each class will already start with their weapon skills learned and will not need to train them later on.
A New Mastery Rating is for higher end character, around 70 and above. This will grant new passives depending on a chosen specialization. All of the Talent Trees have undergone heavy changes, including removal of various Talents and re-arranging where they appear and in which tree. Some abilities that were previously learned much earlier or not even on the trees, have been readjusted to have more core focus at lower levels.
Starting at level 10, characters will gain points to spend in their talent tree and additional points every two levels after. You must spend at least 31 points in a tree before unlocking a new one, meaning characters will now be locked into a role until level 70. However, a secondary tree can be trained at level 30 for 10 Gold, allowing each character to act under two different roles at lower levels. The following pages will go over the newly changed Talent Trees and how the 10 classes work being specialized.
