I think we have had some new stuff - the Whaleship and all the Quests for example.
I'm level 133 with total power over 400K and I can't manage the higher Whaleship levels and am only 1/4 of the way to the Necklace, so there would be plenty of players who still have a lot of stuff to do in the game before the Blooming or other new things arrive.
What I would really like is a "turn 100" card option for events like this. Turning 10 at a time is a bit tedious!
