Assign adds before Archaedas
Uldaman runs long, its stone constructs hit hard, and Archaedas needs a clear add assignment. If the party cannot name the add killer before the event, wait and make the call.
The assignments
Crowd-control stone stewards with Sheep, Sap, or what the group has. In pairs they live too long and drink the healer dry.
Name the Archaedas add killer before activation. Unassigned adds can kill the healer in four swings.
Do not backtrack for skipped quests. The early corridor can respawn while the party finishes the event.
Follow the cleared route
Clear the route and avoid shortcuts. Long respawn timers can turn a backtrack into another set of pulls.
The event needs one add killer
Start Archaedas after the group has named the add killer and crowd-control plan.
