Personally, I really like this change. Given that the rewards are so skewed that anything less than 100% gives significantly fewer rewards, it means that there’s zero tolerance for any issue of any kind - whether that a minor screw up in your game play, or a random network hiccup/disconnect, or a system issue on Flare’s side. Giving some padding here gives a decent amount of tolerance to all of these issues and I think it’s great. In addition, I’m actually much more likely to stay in my “real” bracket based on my actual trophies rather than having to drop trophies before the start of each of these events to ensure I can get 100%. Having 2 extra attempts will probably be enough that I should still be able to get 100% on my real bracket.
That said, I still think they should change the reward structure. e.g. getting > 95% gives some set of rewards, 90-95% gives another, 85-90% gives another. That there’s no longer a huge difference between perfect and less than perfect.
