incredible and extreme lag on the client.

I shouldn't have to wait 10 seconds for the client to pop back up after a game and on top of that, just moving around the many MANY different pages or areas of the client is super clunky and horrible to experience. Why is league the only moba who has a extremely buggy and laggy client? Can we get some change please? I'm tired having to switch back and forth from my loot tab and others just to see if they will load.
