One more reason to wait for the next expansion and get myself a legendary SCYTHE!
This event was one of the rare times that ArenaNet really failed to meet my expectations. They have to go back to the drawing board with future events.
The problem is that they run it on all regions at the same time, so that is the best one. In Europe it's between 7 and 9 pm, mostly. Which is kinda meh for us too.
I wish they would design them to run the entire day and at normal times for each region. But maybe only a 1 time exotic loot.
