I know i’m not the first or last one to ask this question.
Why not hare a spawn in front of your current boss?
If you die in the boss arena you respawn there, you die outside you spawn at the start of the trash section.
Or add some interactable points where Raid Leaders or Asistants can designate Respawn Points.
Ok, if you want to be a “blizzard way” then tweak for specific difficulties.
Smth like:
- LFR - Respawn at boss
- Normal - Respawn at boss if u wipe at least at a specific % (90% or 75%)
- Heroic - Kill the boss once then all future kills on Heroic you respawn at boss
- Mythic - Existing behaviour
I don’t know the perfect system but, as you said, respect a players time.
