For consolidation of abilities, we merged several passive abilities. One notable change is the merging of the Ravage into Shred, and Pounce into Rake; saving a couple keybinds that were only used in conjunction with Prowl. The loss of Symbiosis primarily impacted Druid survivability, as many of the abilities received through Symbiosis were defensive cooldowns. To compensate for that, we improved Barkskin (for non-Feral Druids) and Survival Instincts (for Feral and Guardian Druids).
In an effort to reduce the physical mitigation of some classes, we've modified the amount of Armor provided by some armor types.
