Our group did it twice with BRD, PLD, WAR, and DRG. WAR runs in and links them all, PLD pulls off the Ixali and tanks that while the WAR handles the wolves. (Technically the PLD can tank more than that, I'm just keeping it simple for the purpose of this post). DRG and BRD focus fire the wolves. The Ixali has AoEs so don't stay clumped up. As the WAR of the group, I ran in, had Rampage up, mashed out Overpower and non-combo Whirlwind+Antagonize when I had the chance. The DRG can afford to go all out because even if they steal hate they can survive longer than the BRD at one-on-one. Once two wolves are down the fight is easily manageable, so have the DRG focus on whatever the WAR is hitting.
