Change in Dispel Mechanics
Certainly, the above enormous change comes at a cost. As said above, all healing specs will be enabled to dispel magic by talents, meaning that paladin specs like retribution and protection are going to fail in removing magic and all shamans the diseases and poisons. Additionally shadow priests will lose the ability of dispelling diseases while in cheap Metin2 Yang, which would heavily influence PVP and disrupt the former balance.
