More than a week into the event. I AM NOT IMPRESSED.
The yield/quest in event currency is about the same as previous events, the amount of stars needed to fill each constellation is the same as well.
However, the average yield per chest is WAY lower. Average of all 9 chests is a cost of 40.7 per star to fill, where I usually managed to average a cost of about 28 by taking low-cost chests a lot. There is NO low-cost chest at all to compensate the higher cost chests and even the medium-cost chests only yield 1 star instead of 2. So getting 9 evolutions with normal play already is going to be a serious challenge.
No stash outpost either this time around I guess. It's one of the few things I'll actually buy, did not get that offer this time, and it's one I really keep an eye out for.
Also, the idea of needing 2 of these artifacts to create 1 of the older ones now is even worse than before because the average per chest is so much higher.
It has been suggested often enough to introduce some way to get more evolutions for past events. Personally, I'd like to see each of the evolving buildings become like AW's, meaning a player can have only 1 of each. That would make it less hazardous to introduce a way for players to get those evolutions since it limits the very powerfull effects they can have, which is something the Devs obviously overlooked with the first phoenixes and the brown bear.
