incorrect. I, a S8 silver 3 player, play for vision, build correctly, have good runes and can attain 7-8 cs/min. I see most of the people in my game doing the same, the difference between silver and Gold is small, the only difference is Golds have slightly better mechanics. The difference between bronze and silver gold is game knowledge and application. The difference between gold and plat and diamond is next to nothing except mechanics, not until master do you start seeing proper rotations, well timed grouping and wave management knowledge beyond a simple freeze. While this is NA and it may be different of other servers the largest gap in skill between a single rank teir (iron, bronze, silver ect) is bronze to silver. The funny thing is there are Iron 4 players getting put into games with High Silver players.
