I’m in a 3 day a week guild that swapped factions and servers which obviously slows progression a lot (before I joined) and I didn’t kill it on the first kill because as a healer why would you take a resto druid. I think I was our third kill from memory.
The guilds first kill was like 200-220 pulls or so I think.
The fight isn’t all that tightly tuned over the first 3 phases. Phase 4 is just a burn but it does get a little bit hectic.
It’s your guilds choice to raid 2 nights which obviously comes with its own risks. It doesn’t mean the fight should be nerfed to suit you.
