Initially from reading the cliff notes I thought this dungeon was going to be the Siege of Boralus of Shadowlands... Fear not!! It's doable! The Last boss is somewhat mechanic intensive but fun. Just that fight alone took about 6 minutes to complete. I'll need to shave off some of that time to actually finish the dungeon "in time" for Mythic+ but it's a start.

I'll have a more comprehensive guide once I down the bosses another time, to see more variables.
