SE could take the structure of BA and apply it on new raids.
Let's say for example you have the trash and then for the 1st boss, you have to split your party in 2 (1 tank, 1 healer, 2 dps) and you have interactions to do between the two party (like raid 24 Atomos trash).
When you beat a boss, the progression is saved (like a slot of PotD), so if you leave with your group, you would return after this boss.
And after, you have trash --> boss, or puzzle & trap between or after or before, etc.
I enjoyed BA so, I want to believe we could have this adapted for a raid 8 man.
The sensation of danger is missing in our actual raids.
