@Riot Can we talk about ranked matchmaking ?

I feel like matchmaking needs a more strict algorithm or something. Mixing a wide variety of mmr and calling that a fair and a balanced game isnt right. Once I had a d5 autofilled top vs. a d1 top main. Or when I went against challengers in d4 promos. Where's the logic in needing to defeat challengers to reach d4. Ofc the mmr balanced it so we had challengers too and d5's, meaning d5 players laned against challengers. Those kind of games are torture. It happens a lot and this literally makes league games a freaking coin toss. Makes me feel like I don't have any influence in games, just what the system gives me decides the outcome of games. Not to mention winning and losing streaks that always happen. Won 5 games, oh well, I guess I have to lose the next 5, not because I did bad, but because I got a 0/10 guy on my team this time. I would be really happy if you took an interest in this after years of the same system, and modified things for the better. I want to actually play ranked for the whole season, not stop midway through it every season, because matchmaking is so frustrating.
