This does irritate me a little. I spent half the tournament in the top 50. When I realized that the reward differential was 500 blue dna between 11-50, 51-100, 101-250, I decided I would be fine finishing top 100 and leave it at that. I stopped battling at rank 75 specifically because of the rewards we were informed about.
Changing the top 50 to get those rewards absolutely would have made me push to get into that tier. I mean whatever, it is what it is. But that’s pretty frustrating. We made decisions based on the goalposts set. It’s likely I would have spent money or spent time grinding if I realized the top 50 reward would be pushed.
