Ranked system to oblivion

Ranked has gone to shit these last days gotta be honest. You don't only not get people in your average skill but people who are just either boosted to your rank or god knows what went wrong. My friend is master and had a plat 1 player on his team????? How does this make any sense plat 1 and master has a huge rank difference obviously.

Okay so, i wanna get into another point of view on ranked... I had a huge winning streak i ranked from diamond 4 to diamond 2 but when i kept winning i just got less and less LP every game it started off with 19 lp per game to 10-11 lp per game when i won and when i lost in diamond 2 i lost 18 lp that's almost 2 entire games that u had to win. It's impossible to climb when it's all about the coinflip botlane and jungle and you don't get those often. I do most of my time win my lane and carry as hard as i can but it's very very hard. Winning games over and over again shouldn't make you get less LP this system has gone to total horse shit everything is just wrong and i miss the 5 ranks which made it harder for noobs to climb to actual diamond ranks i hate that so much that it's soooo much easier for them to climb the game is suppose to be hard not annoying, buggy and broken.
