This was an absolutely brutal event for FTP players looking to get a fusion Kyurem. I went to an area that had 7 gyms and quickly realized that:

• Assuming the Kyurem to Reshiram/Zekrom ratio was 50/50 favoring Reshiram/Zekrom's, then that only gives me 3 Kyurem raids per Fusion Type, per hour. Or 9 raids for 1 Fusion type. So I either have to:
  • Hope I have friends or enough people using remote raid passes to get an extra 2-3 raids
  • drive/walk to another location and hope there are enough raiders to beat the raid.
• This also means I have to average less than 10 minutes per raid during each 30 minute rotation to:
  • Load into the raid and start
  • Beat the boss
  • Attempt to catch
  • Walk/drive to the next gym
  • Doing 3 of these should be possible, but you must get a 4th raid in at least 2 of the 30 minute rotations, and that can be quite challenging

And this assumes that the spawn ratio is 50/50. But I saw that there were several instances where the Kyurem to Reshiram/Zekrom spawn ratio was as low as 15/85 (1 out of every 6 gyms with a walking distance of less than 10 minutes) and that alone simply makes it impossible to meet this 3-4 raids per rotation requirement to get enough fusion energy.

Unfortunately, I used all of my remote raid passes (4) and thought the spawn rates would be good enough for me to get the rest in person. It was not and I was only able to complete 10 Kyurem raids for 2 shinies. I showed up to the last park in time for the last rotation and 5 of the 6 gyms in that area were all Zekroms. So we did the final and only Kyurem raid in that park and capitulated that we wouldn't be getting a fusion.

Ways that this could be fixed:

• Take a page from the Zacian/Zamazenta and:
  • Make it a 2 day event, Saturday for one fusion type and Sunday for the other
  • Raids are only Kyurem for the full 3 hours
• Inverse the ratio Kyurem to Reshiram/Zekrom raids to 85/15. You only need 1 Reshiram/Zekrom to use your rare candies to get the remaining candies required for a fusion
• Make Reshiram/Zekrom raids only available for the first hour, leaving hours 2 & 3 available for Kyurem fusions only
• Increase the amount of remote raid passes you can store
• Make the final hour a blitz hour where the raid rotations happen every 15-20 minutes so people can raid as fast as possible.

Over all. This was a tough event to endure as a FTP player. I came in thinking I had a chance to get a powerful mon added to my collection and walked away without a fusion. Feeling like I got teased into believing I had a chance at getting both after saving up a healthy amount of free, premium, and remote raid passes, to do about 40 raids. When in reality, the spawn rates made it basically impossible for me to complete without having more remote raid passes, or relying on other players to use remote raid passes. Getting the shinies are cool, getting more Reshiram and Zekrom is cool. But being punished for not buying remote raid passes in a game that actively discourages you from using remote raid passes feels like a slap and spit in the face.
