Matchmaking is utterly broken.
This is two games played back to back. They're both ARAM. One game, we have 5 unranked players vs 4 golds and one level 6. That is so heavily one-sided I don't think I have to explain why.
Next game is 3 unranked players and 2 Diamond players vs a silver and 4 unranked players.
The games played out exactly as you would expect them to. People have proven that one diamond player can carry an entire team if they're up against players of lower skill levels.
So, why is it like this? For "lower que times"? Who cares about lower que times when the match is decided when you hit the accept button? Now, I get there's niche cases against that, but that doesn't mean the matchmaking is in any way okay. Please, Riot, fix this. Tired of ARAMs and norms just being a roll of the dice. People can't improve when they get 2 diamond players roflstomping the enemy team, and they can't improve when they're put against someone 4 or 5 divisions ahead of them.
