I prefer the short ones. They're more manageable. Long ones tie your city up for too long and get in the way of normal development. Mind you I liked the evolving Phoenix buildings but three long ones in the first 6 months of the year is too many. I'm rather hoping that once the spire gets fully developed that will reduce the need for so many events to keep the players who aren't in fellowships or have reached the end of the last current chapter busy. I long event, one short one like this a couple of FAs and a couple of challenges a quarter might leave about three clear weeks placed split either side of the long event and several partial weeks which as I said will give people a chance to work on their city with out temporary buildings getting in the way.
The long ones are Seasonal Events, so don't expect them to decrease. And not everyone is going to be spending time in the Spire (I likely won't be). The events aren't requirements...if you don't want to do them, you don't have to. That's the beauty of it all.
@TomBrady because technically, we're not even supposed to have quest lists at all, and the lists don't come from the developers. They come from other players who take the time to compile the lists for our benefit.
