Okay, so i have been observing how many people are actually doing a challenge and how much time they have for the last 2 days. And on the last day is a sign of failure. Now i'm not trying to sound mean on that part because of the certain update, but i felt like this challenge is a bit too much for newer players.
The first problem is the amount of people actually aiming for the challenge. As you can see on the first day 68% of them were breeding, but only 20% gave up afterwards on the first day. On the second day 17% stopped breeding after they got the individual score and before the last day the global score is over 2.545.000 points. About a half of the points, which i don't think they are gonna make it. So if there is not enough people aiming for the challenge it will be over 3.550.000 points, which is not enough to complete the challenge.
The second problem is the elements. Electric and Nature elements are not possible via breeding with these two together, as it requires the Gummy Dragon. So if you have a different element dragon with the matching colors, it will have a higher chance. However the Gummy Dragon has a low chance to appear as an egg instead of common eggs of both elements, which is harder for newer players. One player who is lucky enough to get 3 Gummy Dragons would need 2 more Nature Dragons to produce 9 Nature eggs per hour. That's 216 Nature eggs per day! And it's bad enough because people would often stop going for the challenge once they achieved the individual score.
The last problem is the time limit. I know people would complain about the time limit, but that has to be said. The limit of the time is 3 days, and it's not enough for more-experienced player to actually achieved the score of 125 points if not met if they have other things to do. And it's bad enough since the global score is 5 million points, which is a bit too high for those who can't take challenge at all.
So it's not Dragon City's fault for making it too much. It's actually people's fault for not aiming for the challenge more. This is a reason why we cannot get the dragon and might not get any orbs at all. I'm assuming this because if each failed challenge is announced there will be no rewards.
