Is a Balanced Game Too Much to Ask For?

Is your matchmaking algorithm/system so flawed that it's so much to ask for a balanced game? 8/10 of my games are either facerolls, or getting facerolled. Is it so hard to play a game and feel like that was a great game, whether I win or lose? I really don't understand. It's either my team going 50-20 vs them, or the other way around. These types of games are not fun, nor enjoyable. Get your fucking shit together Riot, and improve your garbage B-tier programmers that graduate from B schools. Good thing I go to fucking Stanford for a B.S. in CS, nice to know all the trash programmers end up at Riot Games.
