Version 1.3.0 (Splatoon 2)

"The biggest changes in Ver. 1.3.0 are adjustments to some special weapons as well as some main weapons. In addition to these, adjustments to improve performance of some sub weapons have also been made.

Along with this update, additional adjustments have been made to refine matchmaking criteria in Ranked Battles so players with much closer Power Rating will get matched up even in the same rank. How much ranks rise or fall will be adjusted based on this criteria. The tendency for rank above S+ will not change with this update.

The next update is scheduled in mid-October and will target performance improvement of some main weapons."
