This system is better than 3 revolving chests, in terms of event currency spent per daily prize. Miserable filler prizes is another matter entirely and that is, unfortunately, just a new motto of Inno these days. We haven't seen any time boosters and big KP instants for over a year now.
I got 28 Goblin Gift Shops in my lucky city and 25 in the unlucky one, the max I ever got in the event with revolving chests was about 19 wishing wells in Autumn Zodiac event of 2019. I also got 8 owl artefacts in both of my cities, which is not bad, considering that in some events I got only 7 artefacts. I don't really care about them, because I'm not going to build the Owl. This was a great event for daily prizes, however the only one worth going for was a Goblin Gift Shop, for me personally, none of mana and seeds buildings were good enough to consider and 10 KP daily prize is ridiculous, compared to 30 KP in previous events.
Also, there is a tendency of stopping us from getting KPs from tourneys and events, which is really annoying, since AWs need an absurd amounts of them to level up. It will take me over 10 years to upgrade all of them without using any push accounts and it's very ambitious of this company to think that they will last that long, considering all their recent screw ups and how many players continue to quit this game.
