Hey guys,
don't know whether you already know this bug, but wanted to let you know anyway. So sorry if there already is a post describing this.
The bug is about valor points. When you reach the maximum, you get the buff Valor of the Ancients which increases the valor points you receive by 50%. This buff does not disappear after a server restart (on Wednesdays), but only after you leave the map which your currently playing with a loading screen. This makes you able to complete quests and get 50% more valor points for as long as you DON'T leave your map with a loading screen. So you could e.g. get more points for your quests on the timeless isle.
Hope this can help you.
Cheers Exitas
