Remember the time when Heroic Races were so difficult for a good chunk of many months since the Heroic had a Pure element to them. Clearly, recall the High Snow race having the most ridiculous amount of PvP battles for one node taking like 3 days to do without gems and the insane breeds and hatch items needed. Then High Celestial did the same thing but with fewer items and then High Score. Also liked it when the Heroic Race just repeated the same node items and pools after finishing Lap 10 and the Epic Card Pack given after finishing enough Laps during one race and never again.

Just for anyone who needs to know this. The Second Door in the hard Path is 2 Yellow keys. But the team by that point requires a full team of 6 Heroics and most of the enemies are around level 40 with some empowered to around 1 - 5 stars.

As someone who usually does not comment into general feedback of most events on the forum, I find that this entire event, in particular, is one of the most anti-climatic Dragon City story conceived. I'll break this down into 5 major points on the issues and positives of the event.

1. Lack of Continuation
   I'm surprised that the story managed to not mention other previous dragons from other stories such as Dracon or even Kenny. These characters were already established sufficient enough to have their stories continued on. The lack of any of these characters including Yggdrasil is seriously questionable when the dragons needed for the entire event could have easily been replaced by those dragons. Nyx also proved to have little to no explanation on to what she tried to do since the 15 seconds videos fail to explain what Nyx did. It would have been an amazing chance to bring older story dragons back to stop Nyx as it would have made the Rescue event feel more serious. It's never even explained what happened to them while this event occurred which felt disappointing.

2. The 4 Summer dragons
   Although these designs were well designed it didn't feel worthy to get them and more as artificial progressing. It only got worse when the first event could only give you 1st dragon for free while the others would be obtained far more difficult to get. Sadly it became so much of annoyance to get them that even now I still can't remember their names correctly as they were. Even the heroic become time grinding and somewhat forgettable by the end of the story.

3. Quests
   Half the quests were not obtainable for me as I wasn't able to get all the dragons needed which got me infuriated as the Rescue event proved no empowerment was needed even though it was advertised that would be a significant requirement to complete. If it had no requirements I probably would have more care into these Quests to summon the dragons needed for the Rescue and could have separated the orb rewards more.

4. Rescue
   As other users pointed out already Rescue events have far too many issues that ended happening. The keys could have been removed altogether to make it more fun but instead became an artificial difficulty for what to do. It's either the cooldowns or keys that really need to be changed to make it better. I even had seen people angerly complaining they couldn't get the final reward because of the cooldown in the Raven battle.

5. Transparency
   As a person working for nearly an entire year on a project about Heroic dragons, I was highly excited to release what I had long spent time analyzing heroics in a report around last month ago. That did not occur however since the release of High Positivity made my efforts halted as now I have to account such a big reward. This felt like a huge slap in the face of my work and I felt this could have been more alert in advance of such a big change. Alerts of the cooldowns on the Rescue could have been given on all the Paths along with important tips instead of leaving twists up in the air far longer than they should.

Positives

After all the issues I will admit at the very least the designs of the dragons were well made along with the reward being highly worthy if you were able to get it. However, making it only possible for people spending significant amounts of money on this event should have not been the focus. There's not much I can exactly say as the number of rewards was limited all around. Hopefully, you can improve the next Story event and make it relevant to other dragons from the previous stories and give more context to what is happening.

Well, I got 80 High Octane orbs. They are not of my highest priority right now so they will not get used. Guess I'll have to do trading to get High Nucleus.

Pretty sure the rewards are not out due to every player needing to be verified in their rewards for Lap 20 0r 50 to ensure no one cheated. I'm fine with that if that is/not the case.

By the looks of the Laps above 10 appear to be heavy in the number of items needed for feeding and gold. I heard from my friends that the drop rate of items is lower than they expected it to be.

Sometimes you dread running in endless miles hoping to find an escape to no avail. I've fallen so far into the underworld. Lately, I've been starting to see a distant object becoming more clearer in the distance.

So far I've found a Pure dragon effective to empower or any Legend element heroic as the best choices. I've managed to find success in empowering in High Guardian and a High Comet. They are worthy investments but a Primal might be the best choice to do so.

I fell into the abyss without regret. The last thing I could remember was seeing a red figure in the distance with what looked to be purple crystals. Nowadays, all I can see are the golden gates above all islands.

Often it was strange seeing such extravagant dragons come close to me without a doubt. One of them looked out of this world with some appearing to be far before I was born. I did however noticed how some were far too weak while others rose.
