"As you know, over the course of the past week there have been issues with League of Legends servers that may have had a negative impact on your experience. This is not the quality of service that we strive to maintain, and we would like to apologize for any disruption that this may have caused to your regular gameplay schedule. The stability of the PvP.net platform remains our number one priority, and we are constantly working to reduce service impacting issues such as these.
And so, in compensation for any lost play time you may have experienced, we will be awarding all those players who have logged into our North American or European platforms in the past month 350 Riot Points. We are grateful for your patience, and we hope that this small token of our appreciation helps you along the way to unlocking your next item in League of Legends. Please note that these bonus Riot Points will take up to 72 hours to distribute, so if you don’t get yours right away, don’t worry. They’re coming!
We want to thank you all for your understanding and support, and thank you for playing League of Legends!"
So...enjoy your RP!
