Since the patch I have had an average of about 400-600ms during normal play and it jumps into the thousands during every fight.

I have absolutely no lag with any other games or programs. Only League.

It makes it very frustrating not being able to play a game I've put so much time and money into!

I know it's tradition to break the game every second patch but surely it's a tradition you could do without?

Im having this same ****, since yesterday im having 600-1200 ms from a normal 70-80

same here, internet working perfectly fine for everything else, nothing running in the background, no inclement weather, no sibling downloading porn, just random 300-400 ping on league at the start of every game. sometimes it normalizes back down to 90, sometimes it doesn't, no idea what could be up.
