New Ranked System 2019

In my opinion I think the new position rank system is awful. Where I do see it as a way to make teams more fair because everyone will know their role as well as the rank they're in and you don't have to worry as much about getting that one trick middle lane who is auto-fill support. My problem though with it is the splashing of LP. If doing position ranks, I don't think any of the other ranks should have an affect on another unless your auto-filled as away to compensate for the fact you didn't get your desired role. An example as to how this splash system has screwed me. I went and played adc in a ranked game to test out the new items and figured I could work on my adc rank well I was at it. In the end the game was lost and it ended up demoting my mid rank. I don't know about you, but I don't see how my ability to play adc (probably my worse role) affects the way I play mid and how good I'm at it(My main role).
