I tanked every boss fine with little info, but the last two as feral without Survival of the Fittest. Everyone in the the raid had blue gear from SFK, DM, and WC. We were hard stopped on the second to last boss because we didn’t have reliable interrupts or a priest to dispel the magic debuff. The comp matters for this fight. It should have been a curse instead of a magic debuff imo.
Honestly your skull bash would be more valuable than Survival of the Fittest imo. I think omen would be fine, its really a question of just how much threat can you put out to compete with the dps.
