Riot's matchmaking algorithm is too aggressive at the moment

The elo disparities in high elo games are ridiculous. Even if I wanted to take advantage of positional matchmaking to get a good grasp of top/jg, I can't. Plat 1 and 2 are getting paired in game vs. Master tier players. This makes it seem like even if you have different ranks, you're still at roughly the same MMR.

This begs 2 questions.

1. Why do the players who sacrifice the most suffer the most? Fill players are the worst off for this system's implementation when they're actually more proficient at the game than ANY of their peers, yet now have to play the most games.

2. Why even have this system? When I'm getting paired with Master tier players while playing a role I'm less proficient at (it's not like they're learning roles either since Master+ has 1 rank for all 5 roles), it feels like the system cannot do what it was designed to do, and that the only point to keeping it around is to say, "Aha, we can make this system against all odds." It's pointless at best, dynamic queue at worst.
