With the advent of the patch 3.1, we will mainly go over the classes' changes such as Warlock, Warrior and Druid. Let us take a quick look the changes for them.Changing stances now has a much reduced cost: you lose a maximum of 20 rages, between them, 10 rages with Tactical Mastery. For example, if you have 100 rage and change stances, you will have 80 rages remaining. If you have 10 rage and change stances, all of your rage is lost. In addition, we may change the penalties associated with some stances.WOW GOLD players now gain rage when damage done to you is absorbed, such as through a Power Word: Shield.Blood Frenzy now causes 2/4% physical damage done. Sunder Armor and similar debuffs now reduce armor by 4% per application, and is now a single rank.Creature armor has been globally reduced so that debuffed targets should take about the same damage from physical attacks that they did before this change. The net effect should be that this debuff is slightly less mandatory in Player vs.Environment and is not disproportionately more powerful against cloth targets in Player vs. Player.Not only are we adding increased damage to Arms, possibly through Overpower or Slam but we are looking at granting rage when the warrior blocks, dodges or parries.The last class is the Druid; its changes are as follows:Savage Defense is a new passive ability. When a Druid in Dire Bear form deals a melee critical strike, the Druid gains a damage shield equal to 25% of their attack power.
