Emporia personal events
Other than capture emporium events, I don't even consider the holding them for 60 minutes and 90 minutes events. We either losing a tons of units to hold them for little reward or we play safe and sending just the right amount and never get the event complete. Personally, for the small daily reward for those events, I believe many of us just give it up and not to worry about them.
I believe if you change them all to transport resource event, a lot of people will start doing the event. I never get them anymore because I am simply stuck with the holding emporium event.
