Managed to get everything from event with 3 tavern explorer,trading and some adventures (started event at lvl 42 now 44). key to any event is stock up prior to event, preferably granite ( i had 20k stockpiled). Sounds like you were really unlucky with your searchs, but the more explorer the better for most events (try to skill them). Do 2 or 3 player adventures and swop loot spot and do all the event related quests. The egg buff was a little hard to keep up but trade what you have for what you need, think i managed about an 80% up time. Finally the gems spent on boxs would of probably been better invested in savage scouts.
