Issue #1) Triggered dragon queen. Died almost the instant it did because new health (975 at that level) did not proc. The animation triggered (if only momentarily).
Issue #2) Above would be fine, except it also ran through the full duration of dragon queen during death timer. Afterward it didn’t even begin the dragon queen cooldown, while dead, until the death timer was done some 20 seconds later.
Definitely should’ve gotten the health boost if it’s going to burn the cooldown. If #2 is working as intended (dragon queen duration continues in death and won’t start the 100-second cooldown for the ability in death, then that’s just terrible.
