What does this warband change actually mean? I got a bit confused there
Just look up the previous warband update description.
They failed last time, so current update just made warbands match the previous (2+ weeks old) warband update notes.
How did it fail last time then?
Last time they stopped them spawning at different times of different worlds and stripped out the 'randomness' in spawn times.
So right at the update they all spawned at exact same time and all respawned 7 hours after they finished.
The failing in their attempt to sync them was two fold:
1) Success or failure of the beam makes the camp last 10 or 5 minutes from that point.
2) Camps being purposefully ignored so they lingered for ~20mins before despawning.
Both of these resulted in the exact 7 hour respawns becoming desynchronised.
In case 1 two completed camps could be divided by 5 minutes.
In case two an ignored camp could be offset by much longer.
Allowing warband pk etc to nudge them apart to get 3 a day quickly once more, by passing the 14 hours it should take to get 3 camps (assuming you start timer at camp 1)
This update just flat out changes this: Regardless of how a camp is completed or when it despawns it will conform to the globally synchronised 7 hour timer.
