if you use at weekend your 100% exp boost item + 50% weekend exp this 13k are only killing a bunch of mobs by grinding and befor next maintenance nothing will happend to this quest to fix it until next thursday
I know that grinding mobs during the weekend is probably more efficient than doing quests. However, I'm a bit of a completionist when it comes to questing, and unfortunately, it bothers me that I can't clear my quest log. I love clearing maps and getting 3-4 levels everytime I turn in a log of quests.
