Bring back the old system. Positional Ranks need to go

It might've been a good idea in theory, but the execution is so poor, and there are far more negative effects than benefits for the community. For my one-trick role friends, they don't mind. But for a player like me who plays top, adc, support interchangeably, this system now forces me to play 3 times as many games to climb, and it's honestly not worth it. This system deters players from becoming a well-rounded player, and it forces people to stick with one role. There are also currently many bugs that allow players to exploit and ruin games for others. I've been queued with at least 1 or 2 "off-role" players in my last 20 games, and they don't play well. Because why? It's not their main role.

In the past with one system, even if you get autofilled, it's your ranked game. Your one rank, and if you play badly, you lose the LP. Now? I had a jungler who was a support main for 3 seasons. Goes 0/11, and writes after the game, "only gonna lose 4LP suckers". While I played well (7/2 ) on my main role, but lose -25LP.

Is this fair?

There's also another issue. Whether this is a bug, or part of the new system, I don't know. One of my friends needed one more game for his promos. He was mid, I was top. After we hit level 3, we decided to swap lanes because we had a better matchup. We won the game, but instead of hitting his promos, my friend got LP for top, and I got LP for mid.

THIS WOULD NEVER HAPPEN IF WE HAD JUST ONE RANKED SYSTEM.

You tried to fix one problem, but it ended up bring a plethora of other problems that did not exist before.
