Wow gold players want him out of mana fast.
To beat this setup, you need to maximize your mana; there is no point in LOSing the Hunter while you have Viper on you, so you make them blow their CCs on you so you can mana Burn the Hunter.As soon as the fight starts, have your Rogue get on the Hunter and try to stun him, get Poisons on the Hunter fast and have your Priest mount up and wait until the Druid comes out to Fear him, as soon as that Hunter gets the first Viper Sting on you, sit next to him and spam mana Burn, wow gold players want him out of mana fast, you will get Bashed, Rooted, Scatter Shotted, Silence Shot, but you need to get that Hunter out of mana. If you manage to get the Hunter out of mana, have your Rogue focus him. The Priest should now get behind a pillar, use your Shadowfiend on the Hunter or the Hunter's Pet and put on your MP5 Wand/Weapon and conserve mana. If you see a good opportunity to kill the pet, do so immediately, that does not mean have your Rogue run across the map and make it look obvious, come into LOS, Fear the Druid and then burst him down with Shadow Word: Death/Mind Blast/Smite/Shadow Word: Pain and whatever else you may have in your arsenal. Once that pet is dead your life is much easier, Renew the Rogue and run out of LOS. If the Druid is always keeping you in combat that is ok, only come out to dispel the Ice Trap on the Rogue.
