MMO-Champion.com has noticed a welcoming update in the 4.1 patch. The updates will include a couple of spells that many Hunters have longed for: The Hydra Pet.
The first hint is a tamed pet passive which holds a Hydra icon. The second is the ability called "Bellowing Roar", which reads: "The hydra lets out a bellowing roar, increasing the critical strike chance of all party and raid members by 5%."
