Perhaps S8 staff sees this as "challenging" us higher levels so the game isn't boring. I know when at a lower level I was excited to be able to finish events and get the prize, having much less energy, coin, and resources. But IMO this event makes it seem like we Must use gems/buy packs to finish, which is distasteful.
Here 's to hoping the drop rates increase significantly for the next week! So we can craft everything and finish!
P.S. Oh Baron, can't you find a cache of gears/bird feathers for us?
