WHAT THE FUCK IS MATCH MAKING?

I'm in bronze 5 I queued up for a game and somehow ended up playing against a diamond 5. WHAT THE FUCK! how is that even remotely fair, and how am i meant to enjoy myself when I'm getting shit on by someone who's over 15 ranks higher than I am. RIOT WTF? my team had 2 silver 2 bronze (including myself) and an unranked, the other team had a Diamond 5, 2 silvers and 2 unranked. I usually try to not pay attention to ranks but when there's a discrepancy this massive it's kind of hard to ignore at the end of the match lee sin had 3/5 kills...3/5. how the fuck am I supposed to do anything to someone who's that much better than me. our team didn't secure a single objective the whole game and just slowly lost, it was demoralizing, annoying and all around a shitty time. When can we a matchmaking system that's actually balanced and not just randomly put together by satan's nephew. I think a 3-year-old would be able to make more equal matches just by matching the colours of the different ranks.
