Rank System Idea

Hello Everyone!

I just recently played my first 10 placement games, and obviously the result is very bad. I don't quite understand how does the elo system works this season but I felt like it actually gotten worse than before. I'm not sure if anyone here familiar with CS:GO's ranking system but apparently the points are judge by various performance by the player. For example: objectives, KDA, or cs. We could reduce the amount of LP deducted from the player if he/she performance above adequate, and deduct the usual LP off from the players who are doing bad or even AFK. As I see, the skill required from players are getting less and less. Simply pick a meta champion and snowball is good enough. It is probably where my rank is but I felt like silver, gold or even plat players are playing....not what they should be performing. Just wondering how do people get boosted that high rank and still play like a bronze. Whats the catch here? I'm appreciate that trolls and AFKs have gotten less, but numbers of non-skill players increased by a huge amount.
