People tend to forget where we come from:
You can't have a fire feniks, brown bear, winter, harvest or carnaval set every single events, there are exceptions,
Events are more than 1 main prize.
When events started the main prizes at large events (the prize you had to pay for to get 1!!!) were:
Venars Rock III,
King of the Winter Tower,
Rise of the Phoenix
The great Auction
Most of these buildings except for the the tower king have returned at some point as daily prizes, but they were main prizes for a large event.
also players without prior knowledge would love the new buildings especiially compared to the "old ones".
Setbuildings were overpowered, often abusable, and people complained a lot more than now about evolving buildings that they simply had no room for yet another building, another complaint was that you needed to go for double days (or use diamonds) instead of daily prizes because an incomplete set without its prime building was kinda useless.
And the infexibility with all the warnings if you wanted to move that setbuilding from one place to another in your city.
When events came to elvenar, every event got buildings better than the previous, but that ain't a long time healty road to run.
I to, are unimpressed with the new phoenix, but I do understand that you can't have a better building each time.
You can't and should not compare each building agains the best we had in the past. many many many player do not have the same "history" as you do.
Nor is every "power building" from the past as good as it is, its awesome if that building fits your playstyle but useless if you like to play differently.
