I am distressed by the amount of energy and random drops in this event, too. But if a 14 day event could be finished in 3 days, players would be bored. The other way to stretch an event is dear old Ivy, who was the recipient of our ire all summer. We found out how good we'd had it with Ivy's guaranteed drops, when the troll camp came out with random drops.
Shall we all promise to be uncomplaining if they'll bring back Ivy and guaranteed drops to be the event progress control? I know I would, lol.
