Return Patch 5.12 please game is broken

holy cow ever since this patch has come out I have never had a crummier "for attempt to not be profane" gaming experience! data loss, sporadic ping, extreme frame loss, glitches, display errors, and server errors on nearly every click! jez league is so broken I cant play this game right now. please everyone list your experiences so we can get over this poor patching on a decent game and hopefully get some maintenance soon.

P.S my computer works just lovely, I love my super duper fast internet, and i'm not an IT but I think Riot has enough money and people to do a better job on game performance.
