honestly i never got into that shit of watching pro's i never watch them because to improve, i play to improve...
i got plat by improving by myself
my best suggestions would be, know people which have a ridiculous high normal que mmr, play with them.
when i was like silver i had a dia friend, which i played with i got matched with plats and dias, got stomped several times until i knew how to play against them. that was the best thing that helped me at improving
