A very late post here as this dates back to April 2nd and that meant we’d cleared heroic content more than 2 months before Tomb of Sargeras is released, please Blizzard give us mythic content with flexible raid sizes.
After 3 weeks of working on Gul’dan we decided, following on from a super fast normal clear, to have an unscheduled extra raid for learning purposes. What followed was a single pull kill. Looking back I regret doing this as a few of our core raiders were missing and this robbed them of that first kill feeling despite putting in all the effort. It won’t happen again.
