PSA: Just Play The Game
Looking up ranks etc is actually a detriment to your gameplay. If you look up ranks and see that someone is a higher rank than you, you're going to put them on a pedestal. What this basically does is hinder you from playing naturally. You won't take any risks and will generally play safer because that person is a higher rank so he's obviously "better" than you.
However, if you play vs lower ranked players you'll get an egotistically boost and start making super risky plays because those players are "below" your caliber. This doesn't increase you knowledge or skill level at all. You're basically looking down on people you deem unworthy of opponents, and most often than not, you end up losing vs those very same people.
Some times its better to just kick back and enjoy the game without the stress.
