Hey
Today I was in a World boss group for the weekly mount farm on one of my alts. I did no damage to Galleon, but his AOE got me killed. On my way back (running from the graveyard to my corpse) the boss died, I was still very far out of range. I got the Bonus Roll window to pop up while I was dead, and after checking my /raidinfo there was no sign of being saved for the boss. This could possibly be (ab)used to farm the boss (and mount) on bonus rolls multiple times a week without getting saved.
Edit: Quick steps -
1. get into a Galleon group, get naked (or have very little HP)
2. Get killed (do no damage yourself)
3. Stay dead until the boss is dead, do not come close. (My Graveyard was set to Halfhill, default on a boosted character)
4. When the boss dies, a loot roll window should pop up
5. Run back to your corpse and ress
6. Roll the bonus
7. Enjoy not being saved and return to step 1 until you're out of coins.
