Splatoon has been out for less than a week, but it doesn't appear that Nintendo is resting on its laurels in fine-tuning the online multiplayer experience for it's ever-growing fanbase.
The much anticipated Ranked Battle mode was unlocked only yesterday, along with the all new Port Mackerel map. Today brings the first patch in the shape of version 1.2.0 which states that "Adjustments have been made to make for a more pleasant gaming experience".
Once the patch is applied you'll be able to take part in online battles again. Do let us know if you notice any differences in gameplay and in particular if it is indeed 'more pleasant'.
