Yes, that's correct, but why?
After the last update and increased of the doubloons:
Everyone will (should) get lvl 9 building.
That will produce gold fragment, so with time, everyone will get gold upgrade.. for free.
You CAN pay and have it right away. Fine. That's fair.
As for the calendar - that is PAYING ONLY FEATURE. It is impossible to get the calendar for free. No matter the amount of luck, nobody will have it 100% free. Nobody ever got it 100% free without single diamond in the winter event either. Nobody would have had the calendar in the "before rebalance" system and nobody will have it for free now.
No matter it is not stated in the announcement directly, it is
paying only feature, same like digging the treasure or (in winter) the reindeer sled.
So you can either pay for it or not have it. Simple as that. It is an extra for paying customers, while the main building is free for everyone as it should.
Since the calendar does not contain upgrades for the main building and it has literally only one reasonable item - the skull cave - that's premium building only the paying players will have. I might be jealous of them, sure, but I can understand, that the paying players should get something more which we do not get for free. It is fair as long as that "something" is not gamebreaker giving them such advantage that the non paying players will always loose any battle. And it is not this case. The skull cave has nice extra boost but not a huge one and you can easily get it from other buildings which are available to non paying players.
I was really disappointed (or mad
) about the event when the main building was for paying only players as well. That was bad, unfair. But the last update rectified that, so it is fine now. I still miss the fortune wheel because it was fun. (yeah, I was bad boy. I really needed NOTHING from the wheel, so I was usually spamming the "refresh" button, sorry
), but with the doubloon amount fixed up, this event isn't that bad anymore.
