The idea a silver player knows what silver level is, is the main plague of silver. You're basing how hard silver should be off of basically faulty assumptions. 80% of this game is not skill level at all, and is just understanding matchups and base mechanics. Skill is a watered down aspect of this game, being smart first will make you most skilled. Any team comp you lose to in silver, you can be as likely to lose against bots, and even worse skill level, you lost because your understanding of matchups, not because it's silver elo.
You also play Pyke support and ???? when you get 17/2 and lose, but to everyone else, this is kinda obvious how this sort of thing can happen. It must feel really frustrating to lose like that, but playing a character like Pyke with easy KS potential and no scale makes that sort of thing easy to do.
I'm not going to claim you didn't ult 17 times, I'm just going to give you a friendly reminder your ADC only gets the gold if you land an ult, and in every other case you are stealing the kill. Pyke basically has shit gold scaling, and every kill you get that the ADC doesn't is nearly completely wasted by the time end game rolls around.
