Having just read the developer response to the feedback...
really, you think quests are EXCITING? they're tedious, irritating, and the only reason they get done is a belief that the reward is worth the trouble. P.S. in recent events you've been falling short on that and the increased frequency of them is making it a problem. Hiding eggs was a novel mechanic and i honestly liked the 1 month break from aid chores to keep my actions open in order to egg people back who egged me!
As someone who almost didn't participate in easter on my main server last year, i'll let you know my reason why though: the rewards i wanted weren't terribly obtainable in the shop. I wound up buy large quantities of the random chests not because i felt they were exciting but because the things i had been waiting for to show up weren't available as a pick-what-you-want prize(rogues and SoKs). So i prayed for the 5% or whatever it was chance that a SoK would come out of that silly gold chest and it never did. I built a drummer school and kept it around for a little while to hope it'd get buffed to relevance in later ages somehow, it never did (adding rally AND the armor might make it a wash). My alt servers loaded up on wishing wells, so at least something good came out of that event.
The egg hiding was a wonderful format for an event, and the store was a nice change from the summer casino and winter prize board - if only it had the right items on it. This year's feel's a little too much like winter where it'll be save for a day and dump all your eggs at once, only less reliable. Also the conversion rate of diamonds->average eggs to get a prize you want is much worse compared to buying stars at christmas or tickets at summer. If you cut 1/3 of the price off all 3 chests it'd probably be a better balance both in terms of diamonds to get more prizes and the rate that eggs seemed to be coming in. Alternatively if the chest contents had more desirable things(see below) the price would be fine as is but since likely the only things i want out of the chest at all are the daily special and to a lesser extent the reno kits... it's a bit steep!
Criticism of this year's buildings:
foeberge - supplies, *yawn* - it's fine that it exists but it'll be sitting in my inventory until i decide to build it just to delete it...
deco - meh, some people like to make pretty towns so gotta have one, but *yawn*
color guard - really, did we need another specialty unit that gets outdated some time in the middle ages? what was wrong with applying the champion model to drummers and now color guards where we'd need to reno kit to get them to the right age but they'd actually be potentially useful to everyone? if they kept their movement characteristics it'd discourage using them in the heavy rogue setups so they probably wouldn't even be the strongest option, but hey they might provide an interesting alternative in places.
edit: forgot shrine of inspiration - 3x3? i mean i'm not a fan of getting 1 meager random blueprint to begin with, but making it bigger than the other shrines and on a different period so that it's likely to get out of sync with them over time, yick.
