Yeah, just unsure if they’re referring to your final ranks that show on your stats tab (and then taking your highest split) or your literal final rank the moment the season ends.
A lot of people in past seasons were under the impression that if you hit masters for example, then demote to diamond, you’d get master rewards. That is not true. I thought they may be referring to this in the tweet.
I think the reason that tweet isn’t clear to some (myself included) is because of how splits worked in the past. Just seems weird to re-add splits and then change how the rewards work after 19 seasons.
