I literally cannot find a fun and well balanced match.

I play normals, morons rq-ing after feeding. I play flex, horrendous matchmaking makes the games stomp or get stomped. Then I thought to myself, hey its preseason, don't have to worry about games so much anymore, lets play a game with other diamonds in solo q. I do well mid, but all I hear is "an ally has been slain". So what do I gotta do to have fun in this game ? Do I really have to play riot approved champs to have fun ? Is this what the game has become ? No strategy, no macro, no mechanics, just pick qwer champ that riot approves of being op and spam qwer ?
