For Protector of Droknar's Light
Here there are 2 events that has issues, possibly 3.
1. "defend Droknar's Light from the Invasion" doesn not seem to ever spawn. Haven't seen it once since the launch
2. "Pacify Belligerent Dwarves" has an issue where it sometimes doesn't spawn 1 of the enemies you have to defeat, making it soft locked in that instance.
3. "defeat the champion Engrorged Ice Elemental" in some instances, this doesn't seem to ever spawn.
For Protector of the Beacon of Ages and Garenhoff.
there is only 1 event that never spawns which is the event for "Find garenhoff villagers" Once again, have not seen it spawn once since launch and same for those i've asked.
For Protector of the Skyward Marches
There are 1 even here i've also never seen spawn which is "help the Astral Ward Drive Back the Forged.
And the event to "kill the cmapnion Avatar of Regret" seems quite rare to spawn, only seen it once. But might be tied to the event mentioned above. not sure quite yet.
