Guild Wars 2

At the Seraph observers waypoint in Brisban wildlands, I always observe the same: endless waves of bandits charging in on the little outpost, with all the NPCs dead there.

It looks like a “defend the otupost from bandits” event type – but there’s no active event. Just waves upon waves upon waves of bandits. Even if all the NPCs are resurrected, as soon as players leave, the bandits slaughter them instantly (the bandits could use an adjustment in difficulty. No other foe, bar Orrians, is quite as difficult to deal with, with all the ranged weaponry, fire fields and Knockbacks and knockdowns).

Is this possibly a bugged event? Event concludes, but server forgets to stop spawning the bandit waves?

The caravan’s event ends up the hill from the camp is why you hadn’t seen an event marker there. That event doesn’t seem to have any bearing on the bandit onslaught, though.
I’ve never seen an event involving those bandits, they’re always just permanently slaughtering the entire camp and anyone unlucky enough not to realize they don’t stop coming.

I reported this in the beta as a bug. It’s been around for ages and as far as I know, there isn’t a way to stop them from spawning so quickly.

It feels like it shouldn’t be happening and was maybe an event they removed and just forgot to remove the scripting for it, or it’s just a bug in the spawn rates. It may be worth posting it in the ‘mob respawn rate’ thread and see if you get a response.

Endless waves of bandits should make a decent farming spot at the very least.
