Resto Druids and Holy Paladins in particular were able to attain levels of physical damage reduction akin to a PvE geared tank thanks to their naturally high armor, and high resilience. This change will essentially deflate the value of healing by an amount roughly similar to the amount of damage reduction provided by the changes to resilience.This should make life a little bit easier for damage dealers, but it'll still be quite a task to take down a healer without someone applying a wound effect and interrupting casts effectively. Many players were expecting a change of this nature after the resilience buff was announced. The general consensus on Arena Season 7 was that there was simply too much burst in the wow gold game, and that damage and healing both needed to be toned down so that games could last longer and be more strategic. The final straw seemed to be the now infamous grand final match at MLG Orlando in January, which spurred complaints from the arena community on the issue.Although a 4% reduction to stamina can't be a source of joy for Paladins, I think that many of them are secretly relieved that they got off with such a minor nerf. Paladins have been the go- to tank for raiding since the buffs to Ardent Defender in Patch 3.2. As Crygil noted in the post, that ability is one of the most, if not the most, powerful tanking ability in the game right now. I doubt that this change will have any effect on the use of Protection Paladins in raids.
