Riot i think you have to explain more about the new rank system

In the video I'm pretty sure that you guys did not clearly go through the whole LP system. I drop more LP then i gain when i win. while you also did not explain how the game play of a person could affect the drop of LP, like i got a decent score while my team feeds and i drop 22 lp, but i only get 16 when i get s+ carrying. Players are also treating rank as a mode to troll or don't take it serious especially due to the new rank system. i really wish there could be explanation on this system and changes to it.
