Reward imbalance affects player behaviour
This is happening on Tarnished Coast as well.
I was on last night at Isle of Janthir and we killed her twice and the vendor came up. Risen respawns instantly and we fought them off to allow people access to the armor. I didn’t need armor from this vendor but I still helped out twice on this crazy event.
The reward/drop system in the game is borked in general and really needs a thorough overhaul. I don’t see that happening all at once though. I reckon that they felt so liberated from the necessity to eke out rewards in GW1, that they went to the opposite extreme of dropping “rare” items like confetti, with the result that there was nothing special left to put in high level mobs and chests.
