Balance changes
"The changes in this update are designed to lower the abilities of a portion of all weapons and specials that, based on analysis of statistical data, had obtained an advantage in results.

Our intention is that this will entice players to explore these weapons, while retaining their individual strengths of the weapons in scenarios where they are advantageous.

We reference various sorts of statistical data for these adjustments, but in particular for those which lower the abilities of certain weapons, we've focused on data from matches between players of high Rank.

We will issue future updates after looking carefully at changes resulting from this update, as well as the overall state of statistical data over the long term."

Trivia

Nintendo of America's website lists the update as releasing on 2020-04-15, indicating that this was potentially its original planned release date.
 * Similarly, Nintendo's Japanese website originally listed the update as releasing on 2020-04-20 before correcting it.
 * The English translation of the patch notes contained a small mistake: the update notes for the Baller stated that its updated effect with the Custom Explosher was in regards to a fast weapon, not a slow one.
