My thoughts about the event; this is from the perspective of a player at the end of the tech tree - nothing to research, long scouting times but lots of space for shanty towns. It may have been a totally different experience for other players.
Most importantly, the quests have been doable, and rather easily so. Thankfully the quest have been changed from beta. There were way too many encounters and too much MA centric quests to call it enjoyable for me. The Phoenix event was much better in that respect.
The Stonehenge building is neither good nor bad if you can evolve it to stage 8+. Some of the dailies were great though - some of the best buildings ever, or time boosters.
Still not a fan of the rotating chests, and probably never be. However I cannot complain about the overall result.

The worst idea IMO, was to add sun flares to the mystical object. 37% chance to win 150 sun flares, and 37% less chance to win 500 dias or 50 KP
. I will have to wait until the event is over before collecting the object
.
Another very bad idea is to change daily prizes. Please leave them as published on beta. I know that you can do that and we must not expect that the prizes remain the same, but I think a game should be fun and replacing prizes just isn't.
Summary: Great daily prizes, but considerably less fun than the Phoenix event.
