We spent 2 night progressing on Primordius hc when suddenly warlocks and boomkins (Symbiosis) massdispel no longer worked at dispelling one of the 5 active buffs. Seemingly they hotfixremoved those dispels effect in order to prevent guilds from using that tactic on Primordius. I'm annoyed that we wasted 8 hours doing that tactic just to be spat in the face and mocked by guilds who have already gotten past the boss using the tactic, but in the end I'm overly pleased with our new tactic. It's alot less clunky and much better dpswise (hard to believe, but true).
About letting the debuff drop on its own. No just no. And do not Unbound Will it without having Sac Pact or Unending Resolve running, the damage is too great and we warlocks know how healers like to react to spike damage on random raid members, effectively not healing the tank anymore, who then dies. GG atleast the warlock was saved. Hnnng.
