Matchmaking system

from time to time i keep questioning myself, does matchmaking system "see" me as a worser player after i lost cca 6 matches in a row? my eperience shows me that it doas and my opinion about it is that is a slappy and superficiall way of matching players together

I don't say this without any logical reason, of course :

                                                                                      when i win 5 in a row i get matched with platinums, golds and silvers (even thought i am not a match for platinum or gold),and when i tested some buids with which gameplay didnt turn out good as i expected and lost about 8 games in a row i keep geting matched with bronze and under  lvl 30 (talking about normal games)

this is pretty much anoying on rankeds as on normals(2 wins, i get extra low team against extra high enemy)

Why we couldnt get the system whitch uses only overall progress of a player as a criteria? why matchmaking system couldn't be set so that we could actualy know what to expect ,in other words why the analizer of the players wouldnt be slower and more stabile?

I expect coments that are actual locial reasons, not answers like adapt(because i am adapting) ,don't test what you dont know it will work and so on.

i dont wanna play with players, (just because i had few bad matches ),who doesn't know that kills dont matter so much in matter to win, players to whome i need to tell to destroy towers over and over and then at the and i am the one who needs to destroy first tower so they could have a curage to do the second,players who are deaf to pings and so on . Bronze and leveling up are much behind me and honestly i dont want to come back ,not even for short time...
