Druid Resto Overpower:
Hunter melhorou contra caster no PVP:Lifebloom: Mana cost of all ranks doubled. When Lifebloom blooms or is dispelled, it now refunds half the base mana cost of the spell per application of Lifebloom, and the heal effect is multiplied by the number of applications.
LOL:Viper Sting redesigned: Stings the target, draining 4% of mana over 8 seconds (up to a maximum of 8% of the caster's maximum mana), and energizing the hunter equal to 300% of the amount drained. Only one Sting per hunter can be active on any one target.
You no longer need to learn cooking from books. The trainers have finally done their reading and are able to teach you the same thing.
