Riot please fix your client

Before i go on let me say ive never had this problem before ever. So this week rengar is free so i decide to play some normal games and i get into a blind pick game and the lobby goes and the game loads for some reason it takes extra long for the load to pop up and extra long for me to load then im stuck at 100% for like 5 minutes it then says your internet has disconnected please reconnect but my internet was FINE i was actually reading a boards post during loading so i reconnect 2 or 3 times same thing happens so then i close client completely and try again same issue so eventually i give up and let the game play out and take the afk, after the game finishes i go into Q again get another game and the same thing is happening right now AGAIN, FIX YOUR CLIENT
