Ping is the ability for your computer to talk to the riot servers. Having a high ping is most often caused by your local ISP and not anything riot has done. If there are issues with riot servers, they will effect all players. Turn off your porn downloads, youtube streams, pandora music, and torrents. Riot created a knowledge base for people like you. Click on the support button at the top of the page, go to the knowledge base and optimize your system.
I promise you that the problem with your ping is you, not the patch, not the game and not riot.
