LEAVER BUSTER vs AFK,UNBALANCED ASS TEAMS.

I have been playing league ever since it came out in 09' and still playing to this day. I mainly play rank and I do enjoy the gameplay and challange but the thing I don't understand is why is it so unbalanced? To start a game you go through all the process to get it going then boom AFK??? of course you continue playing since its rank but the morale is down everybody has to play 2x harder. You match people with their current rankings understandale but wtf one sided games always ONE SIDE FEEDS A DAM STORM and here comes all the BS whos fault it was yadi yadi'. Im not the best player but I sure ass hell do play it accordingly. So what im trying to get at is how can you tell whos fibbing on the reports and not? Trolls everywhere will try to get your shit banned for no apparent reason other than "hey you didnt die as much as I did" therefore ima report your ass?? People who spent money on this game should get some kind of reassurance that our investment doesn't go unnotice.
