Zenimax has slowly but surely been increasing the number of items available per event, while raising the bar for earning said items. Their overall goal is clearly to drive more people to purchase event tickets in order to purchase items from the event vendor, which is going to be a hard no for me. We're four days in and after opening 4 strongboxes, I still haven't seen my first fragment.Given that the fragments cannot even be traded or sold, and with feathers, berries, and fragments all available, the only way to get everything is going to to break out your wallet. Between the lack of fragments and the poor server performance (lag & disconnects) in Murkmire, I'm going to go ahead and not bother with the remainder of the event. Just my two cents.
Edit: We're actually 4 days in and still no fragments.
