Ladder reset and Official Ladder Tournament
As we continue to work to reform the ladder system for PS, the ladder ranks are now reset among our formats. This is occurring in preparation of a fun Official Ladder Tournament that will be hosted by Smogon's TD team, with the intent to increase ladder activity and quality. This event will be using the ORAS OU format, and there will also be an official PS room that will be setup solely for this tournament. Check it out -- we hope to see a nice turnout among the competitive scene!
