Well it made me go to the Clockwork City. Hadn't got there yet.
Event Ticket requirement was tedious but never took too long. I did the World Boss quests. Would have been better if there were more WBs! It was repetitious, and I hated having to race around trying to gather things for the non-boss requirements, along with dozens of other players.
As a tank spec, I never got any loot from the World Bosses. I hate that only so many people get loot. I probably enabled dozens of people to get the loot drops by absorbing agro that would have killed many players. This was the biggest negative for me, even though it's not even event related.
On the other hand, the loot was pretty poor though, and I wasn't looking for anything from the bosses or the coffers. I only did one quest per day to get the event ticket. I felt no desire to farm anything in Clockwork City.
Double resource drops was a joke. I don't think I ever saw a resource node.
I am afraid my experience was fairly negative. I did it for the Event Tickets and derived zero fun from the experience. Compare this to the Witches Festival, which was super fun.
I don't think the double resource, double quest drop event really works for small zones. It works for Wrothgar, and Vvardenfell, and other places with more content.
The event never took too much of my time, so my overall rating is "meh".
