Fixed
Hey summoners, earlier today there was a server issue with ranked games that caused LP calculations to be slightly less favorable for players during this period. In other words if you lost a game you lost more LP and if you won a game you earned less LP. The issue should now be fixed in all regions and ranked queues have been re-enabled. If you played a game during this period you will see improved gains and smaller losses for your next few games to compensate for the poor gains from games won or lost during this period. Also, any wins and losses that occurred during this period will be calculated correctly in terms of how they factor into your placement for the 2014 season.
Some concerns were brought up about clamping as it was especially harsh when this issue was occurring. I want to reaffirm that clamping will be removed at the start of the 2014 season for all divisions except diamond 1.
