This game sucks

I have a higher overall rating but I always lose to players with lower overall ratings! I play the manager mode every day! Shouldn't this mode have better players and win? If not, why do we spend money on so many player packs? I can't understand it, it's illogical! EA has its own algorithm and its own script! They don't want to change it! I went from eighth place in the leaderboard to more than 1,000 in two days, and I lost 150,000 points! Isn't this manipulation by you? They won't admit it! They just want to make money! Players' feedback is useless!
