Explain Ranked Matchmaking To A New Competitive Player

You have won four in a row and your rank has barely budged, which feels like the system is broken. This explains matchmaking rating, why hovering near fifty percent win rate is completely normal, and what to actually focus on instead of obsessively tracking every win and loss.

**Explain the system in plain terms:**
1. How matchmaking rating actually works, distinct from the visible rank tier
2. Why win rate near 50 percent is normal and expected, not a sign of being bad
3. What causes rank to feel like it is not moving, and what usually is a genuine skill signal versus normal variance
4. Two realistic things to focus on improving instead of just tracking wins
