Bug splatt

I'm sick of this I play my first rank match and I get bug splatt so I leave the client to fix it just to get a leaver buster! This is outrageous riot! I get leaver buster and a loss because of this that's not even right! I take fixing the error in my own hands just to get punished for your mistakes with your client this is just outrageous and I demand that there should be a system to resolve this!
