I would like to present a tale of two cities (and a 3rd more normal one):
The best of times: On carthage this event my luck has been *insane* - I have finished 7 toy sets, and am up to 10 of the monkey - just betty lou holding me back. I won 17 dauntless towers before I'd gone and gotten all the extra tools from the toy sets. Unfortunately that's all I had any interest in other than the grand prize and that was for one day's testing (which i'm glad for). Since then I haven't tracked what I've won for specials. If I'd worked the calendar I'd be sorely tempted to spend some diamonds to finish a second caravan - but instead I just have a bunch of wildcard pieces.
The worst of times: On dilmun I was eagerly looking forward to a halloween event finally having better special chances - along with just generally new stuff for an assorted city. I never did finish a full toy set (missing betty lou again) - but got a lot of the toys I was looking for and did go broke on coins multiple times completing them for goods
My goal was a completed asylum and a few stage of ages. I wound up with a few stage of ages and an asylum stuck at level 7 including the one from the prize track (I didn't expect it to come back as a special late because of the experience on beta so I didn't save currency to finish it when it did - with a few days left I went after reno kits as they were at least something useful - and think i got a couple). So I'll have to wait for the antique dealer to save me.
Curious as to which experience was more normal, a 3rd city for comparison: I also only really cared about finishing the caravan there, but had been procrastinating all event (didn't even spend a ticket til today). It did win at least 1 of each toy though I won't actually be bothering with them (and 3 of the monkey - once more betty lou was the one I was short on for multiple sets - but nowhere near the set after set after set that I won on carthage. It won ~12 specials (about 3-4 more than dilmun in total and it would've been some hundreds of tickets behind in currency to spend because it didn't run any of the toys) leading me to believe that these cities were indeed outliers. Dilmun's kinda been cursed since it opened for me!.
