Ranked in silver are luck based
One team is gonna have afks/autofill/ lvl 2 ragequitters Just gotta pray it won't be yours. Gotta love this gameplay honestly, climbing based on luck, people sure talk madshit about TFT being an RNG based game, but I actually feel that more in the summoner's rift.
Also I want to point out the huge matchmaking problems, As a silver 2 I shouldn't have a Silver 4 to Bronze 1 team and be fighting against Silver 1 to Gold 4 ennemies
