Patch version 1.27.53

Open Beta Patch Notes

PVP.net

Improved Leaver Buster – PVP.net will now automaticaly ban leavers. This works similar to a ‘driving points” system for driver’s licenses.
-You gain ‘leave points’ by leaving games, and if you have enough leave points, you will be suspended or banned.
-You lose ‘leave points’ by having good behavior – by completing your games, and not leaving over a long period of time.

Mastery saving has been improved
Repseccing your masteries no longer saves an empty mastery page to the server. This means you’ll never accidentally enter the game with no masteries.
You can now remove saved mastery points individually without having to return all your points.
When you have unsaved changes in your rune page or mastery page, you will now be prompted to save when navigating away.

Lowered the volume level of audio in PVP.net at all slider positions. You may want to adjust the audio levels in PVP.net as a result.
Fixed a bug where viewing another users Champions would display your own Champions instead. This option is now greyed out when viewing another users profile.
Fixed a bug where the “Play Again” button would not work at the End of Game screen for arranged teams
Fixed a bug where you could not select the “Random” marker in Champion Selection
Fixed a bug where PVP.net would crash at certain resolutions

Trundle, The Cursed Troll (January)
