If you're anywhere near close to silver in skill level, games in silver are literally 100% luck, based on who has more trolls. No, not just the guys that run right down mid and feed. Also the people that are playing a champ for the first time in ranked. Also the people that are 0-3 and continue to all in their enemy laner and feed more. The people that AFK (which riot has stated that no matter how many games you AFK in, you will never get banned).
Also, a little while back, riot HALVED the XP require to reach level 30. So you have more players in ranked having absolutely no clue what the fuck they're doing. It's not their fault, it's the morons that run this company's. Now why is silver a bigger shit show? Because they throw everyone in silver. You have to literally try to get placed in bronze. And once you're placed in silver, it's practically impossible to get demoted. You have to lose like 100 straight games.
Furthermore, trolls are not punished unless you're "mean" in chat as well. They've been trying to solve "toxicity" for the past 4+ years by just throwing chat bans and bans on everyone who "flames". Not going to fix the underlying issue here. Should be obvious after the past 4+ years, but for some reason it isn't.
