At least EU server(s) already reached the summerfest event. There should be a camp of the event in the middle of Tempest Bay. There seems to be 2 quests obtainable. In my opinion those are 50+ level.
So the exploit part comes here:
Get both quests, relog and done. You should be able to complete the quests.
You get money and some other rewards.
Have fun.
I'm not sure if those are dailies so will try to remember to update asap.
