From silver to gold

finally i hit the gold 5 i was silver 4 and took me 138 ranked games (46 hour only doing ranked mode)78w-60l.
i remember i win all the 3 placement but they put me always on silver nvm.
just to inform you the state of the game and no im not a bad player but in these games damn i have seen everything

yeah it doesnt matter if you climb unless you steadily stay in the upper league for about 3 seasons in a row, otherwise it just checks the last few seasons and its silver no matter what. Thats basically it.
