Hello everyone,
I don't know whether it still works after the last update of the update, but there was a method how to get round the fatigue
We (me & clan mates) observed, that fatigue cuts off a part of base experience and CHG bonus, the GRP bonus stayed the same. So in a group of (optimally) 5 people, there is still a high potential to level up fast, because in 5 ppl the base and challenge xp is less important than the group bonus and the killing speed (harvesting)
And also it's safer then grinding alone, right?
I would like to recommend people to kill mobs in parties instead of saying "stop ks noob"
