I play different elo-rated games for the past 13 years and completely disagree with you. 50% is very healthy psychologically as it keeps you humble and challenged all the time. If your play improves to ~55% win rate, you already feel highly rewarded and most of the reward feelings come from the fact that you now play on higher elo. You don't care about single losses/wins anymore.
