Why am I not capable of winning against Gold players?
Start of the season, I got placed Gold 4 and climbed to Plat 4 in 25 games with a 90% winrate. Then I climbed to Plat 2. At this point my MMR was at least D4+ because I was playing with/againt P2 - D3 players almost every single game. Then something happened, got demoted to Plat 3, got demoted to Plat 4, and I've been Plat 4 for probably 100 games now. I get placed with low golds every game, who feeds almost every game, and I face golds who do better than me at every aspect of the game. I lose to Gold players in lane.
I'm just completely lost as to in the matter of one month I go from winning against Diamond players to losing against Gold players. I haven't played less than usual, I havent changed the champs I've been playing, I just lose.
Got a Challenger coach by the name of "Epique" who suggested: "You are the unluckiest player on Earth" "Stick to Kaisa because the botlane meta is broken as of now".
I just don't know how I can go from Gold 4 - Plat 2, 90% wr, 1v9 Twitch almost every game. To losing, every, single, game, against worse players.
Edit: I'm losing to Silver players now.
