I know this answer is months late, but on mythic, when a player goes into the shadow realm, everyone else gets a stacking bleed and slow. At this point in the fight, the entire raid is going down, so if Meeres doesn't get BoP, he gets 19 stacks of a bleed and a 95% slow.
Quick question, @4:08 what is the purpose of the BOP?
