I think it may be possible to bubble/IB your own stacks. But i’m not sure i understand why it’d help you cheese the wave? Would you please like to explain?
It could also not be possible, as in the video, it may be a bug or something but i think dead people keep their stacks when they are ressed. At 1:05 you see the DH tank with 40+ stacks being rezzed and having the same amount of stacks (check raid frame). It would mean to me there is no way to totally reset your stacks without going through fragments.
Bear in mind that if the fight mechanics stay more or less as they are, we will need people to be hit by the wave to spawn enough essence fragments for the tanks, as it’s the most reliable way to spawn a lot of fragments for them to keep their own stacks as low as possible. Of course, without any stack you are 100% safe 🙂
Anyway we’ll need to define what’s the highest amount of stacks you can keep and stay safe, so at some point it’s possible some people should not take the wave.
And finally, the boss may have changed quite a bit right now, even if most of the fight mechanics should be the same, the exact way how they interact with the raid is subject to change.
